- the grooves conduct liquid toward the shoe perimeter (i.e., away from weight-bearing and contact surfaces), and the siping aids by wiping the contact surface, thus improving the friction between the contact region and the ground and reducing slipping and hydroplaning.
- the wiping edges enhance the wiping of liquid into the grooves.
- the contour of the wiping edges assures that wiping will occur even when the shoe strikes the ground in directions oblique to the longitudinal axis of the sole.
- the void-to-contact ratio of gap area to contact area enhances both the conducting of liquid away from the shoe and the frictional slip-resistance of the contact region against the ground.
- the size of the channels assures adequate space for the conducting of liquid, and the angle of the channel walls minimizes the accumulation of small objects in the channels.
- the large angle between the channel walls and the contact region aids in ejecting foreign objects.
- the sizes of the friction pads aid in their flexibility, and enable the friction pads to move independently of each other to provide good contact with the ground even during unusual foot movements or uneven weight distribution, e.g., movements on boat decks.
- the friction pads and bars are large enough to reduce the likelihood of damage to them.
- the sole effectively grinds particles, e.g., food, lying on the ground, thus reducing the likelihood of the user slipping.
- the shock foam inserts reduce shock to the user's foot, and provide more uniformity of pressure distribution to the bottom of the outsole.
- the flatness of the contact region improves the slip resistance.
- the bottom surface of outsole 10 (men's size 10) has a tread pattern with sixteen transverse wavy grooves 12 on the toe and heel areas.

- Between adjacent groove pairs 14 are friction bars 28, each of which is at least 3/8", and no longer than 0.60", preferably 1/2", long (in the direction of longitudinal axis 18).
- Each friction bar 28 in the toe area bears a siping pattern 29 of three wavy cuts which undulate like grooves 12 (in Fig. 1, the siping is only shown on one of the frictions bars).
- Each groove 12, by virtue of its wavy contour, has some sections which are perpendicular to axis 18 and other sections which are at various oblique angles to axis 18.
- the heel portion of outsole 10 extends forward into the medial region to define an arch support 33.
- grooves 12, 16, 20 are 0.080" deep v-shaped channels whose side walls 34 meet the bottom surface 36 of outsole 10 at an angle of at least 105° (preferably 110°).

Abstract
A slip-resistant shoe sole (10) comprising an outsole layer having a bottom surface defining a region of contact between the sole and the ground, the outsole layer bearing a plurality of channels 12, 16, 30, opening onto the bottom surface to define a pattern of elongated gaps across the contact region, the ratio of the area of the gaps to the surface area of the contact region and the configuration of the gaps being arranged to effectively cause liquid between the contact region and the ground to be conducted away while enhancing the slip resistance produced by the contact region engaging the ground.
Description
- The invention relates to slip-resistant shoe soles.
- Slip resistance can be improved by special tread patterns in the bottom surface of the outsole, and by siping the bottom of the outsole (i.e., incising parallel wavy cuts).
- In general, the invention features a slip-resistant shoe sole comprising an outsole layer having a bottom surface defining a region of contact between the sole and the ground, the outsole layer bearing a plurality of channels opening onto the bottom surface to define a pattern of elongated gaps across the contact region, the ratio of the area of the gaps to the surface area of the contact region and the configuration of the gaps being arranged to effectively cause liquid between the contact region and the ground to be conducted away, while enhancing the slip resistance produced by the contact region engaging the ground.
- In preferred embodiments, the outsole layer bears a plurality of siping slits (preferably only in the toe area); the ratio of the area of the gaps to the surface area of the contact region is no less than 10% and no more than 40%; each gap is no less than 1/16" wide; each gap is bounded by wiping edges where walls of the channel meet the bottom surface, the wiping edges being contoured to include sections perpendicular to a longitudinal axis of the sole and sections at oblique angles to the longitudinal axis, whereby liquid between the contact region and the ground is effectively forced into the channels and conducted to the perimeter of the sole, enhancing the slip resistance produced by the contact region engaging the ground at an angle of attack either along or oblique to the longitudinal axis; the portions of the contact region between the elongated gaps include friction pads no shorter than 3/16" (preferably 1/4") in their shortest dimension and no longer than 0.60" in their longest dimension; each channel has walls which meet the contact region at an angle greater than 105° (preferably 1100); the friction pads include friction bars which run transversely across the sole and bear siping slits to improve slip resistance; each friction bar is at least 3/8" (preferably 1/2") and no more than 0.60" in the longitudinal dimension, and bears at least two siping slits; the channels include a plurality of parallel transverse wavy grooves spaced apart along the length of the contact region, the wavy grooves are paired, the grooves of each pair are connected by a plurality of straight grooves to define a sequence of friction pads between the grooves of each pair, and successive pairs of the grooves are separated by friction bars which run substantially uninterrupted transversely across the bottom surface of the outsole layer; at least some of the elongated gaps are arranged in a pattern of concentric arcs centered on a point in the ball area, and adjacent elongated gaps are connected by straight gaps oriented along radii of the pattern; the sole includes shock foam inserts in the ball and heel areas; the sole includes siping (three parallel wavy cuts undulating the same as the wavy grooves) on at least some of the friction bars; and the contact region is flat.
- The grooves conduct liquid toward the shoe perimeter (i.e., away from weight-bearing and contact surfaces), and the siping aids by wiping the contact surface, thus improving the friction between the contact region and the ground and reducing slipping and hydroplaning. The wiping edges enhance the wiping of liquid into the grooves. The contour of the wiping edges assures that wiping will occur even when the shoe strikes the ground in directions oblique to the longitudinal axis of the sole. The void-to-contact ratio of gap area to contact area enhances both the conducting of liquid away from the shoe and the frictional slip-resistance of the contact region against the ground. The size of the channels assures adequate space for the conducting of liquid, and the angle of the channel walls minimizes the accumulation of small objects in the channels. The large angle between the channel walls and the contact region (i.e., the high draft of the channels) aids in ejecting foreign objects. The sizes of the friction pads aid in their flexibility, and enable the friction pads to move independently of each other to provide good contact with the ground even during unusual foot movements or uneven weight distribution, e.g., movements on boat decks. The friction pads and bars are large enough to reduce the likelihood of damage to them. In embodiments having grooves in a concentric arc pattern in the ball area, the sole effectively grinds particles, e.g., food, lying on the ground, thus reducing the likelihood of the user slipping. The shock foam inserts reduce shock to the user's foot, and provide more uniformity of pressure distribution to the bottom of the outsole. The flatness of the contact region improves the slip resistance.
- Other advantages and features will become apparent from the following description of the preferred embodiments and from the claims.
-
- Fig. 1 is a bottom view of a shoe sole according to the preferred embodiment;
- Figs. 2a, 2b are cross-sectional views taken at 2a-2a and 2b-2b of Fig. 1 and showing respectively the wavy grooves and the Littleway groove in the preferred embodiment;
- Fig. 3 is a top view of the preferred embodiment;
- Fig. 4 is a bottom view of an alternate embodiment.
- Fig. 5 is a bottom view showing representative alternative siping patterns.
- Referring to Fig. 1, the bottom surface of outsole 10 (men's size 10) has a tread pattern with sixteen
transverse wavy grooves 12 on the toe and heel areas.Grooves 12 are arranged inpairs 14, with the grooves of each pair connected by shortstraight grooves 16 each of which is oriented perpendicular to the two grooves of the pair and oblique to the longitudinal axis 18 of outsole 10. Eachgroove pair 14 extends from one side to the other side of outsole 10 in a region outlined by Littlewaystitching groove 20 which follows along the perimeter of outsole 10. In the toe area, theaxis 22 of eachgroove pair 14 is oriented at an 80° angle to axis 18. In the heel area, eachgroove pair 14 is oriented perpendicular to axis 18. In each groove pair 14 (except for the rearmost pair), one of thegrooves 12 has anextension 24 which passes beyond Littlewaygroove 20 to the very edge of outsole 10. Within eachgroove pair 14, a row offriction pads 26 is defined bygrooves adjacent groove pairs 14 arefriction bars 28, each of which is at least 3/8", and no longer than 0.60", preferably 1/2", long (in the direction of longitudinal axis 18). Eachfriction bar 28 in the toe area bears a siping pattern 29 of three wavy cuts which undulate like grooves 12 (in Fig. 1, the siping is only shown on one of the frictions bars). Eachgroove 12, by virtue of its wavy contour, has some sections which are perpendicular to axis 18 and other sections which are at various oblique angles to axis 18. - The heel portion of outsole 10 extends forward into the medial region to define an
arch support 33. - Referring to Figs. 2a, 2b,
grooves side walls 34 meet thebottom surface 36 of outsole 10 at an angle of at least 105° (preferably 110°). The corners whereside walls 34 meetbottom surface 36 formwiping edges 35. Eachgroove gap 38 of no less than 1/16" (preferably 0.080") inbottom surface 36. - The void-to-contact ratio of the contact region of the ball and heel areas (i.e., the ratio of the area represented by
gaps 38 to the aggregate area of contact between the ball and heel areas and the ground) is between about 10% and about 40%, preferably about 20%. - Outsole 10 is molded of rubber (available under the name Sperry compound from Goodyear Tire & Rubber Company) having a durometer of 60-65 shore A. Outsole 10 is molded with the
bottom surface 36 as flat as possible, minimizing doming or curving, to increase the contact area. - Referring to Fig. 3, outsole 10 is molded with recesses in its upper surface to receive
shock foam inserts - When outsole 10 strikes a wet ground surface, the
wiping edges 35 wipe the liquid intogrooves Extensions 24 further conduct the liquid away from the outsole. The pressure between the ground and friction pads andbars grooves bars - In one test of the coefficient of friction of an outsole like that of Fig. 1 (but having two siping cuts per friction bar rather than three), a resin surface, simulating a fiberglass boat deck, was flooded with water and the sole (which was pressed against the resin surface by weights) was caused to slide both along the longitudinal axis of the outsole and in directions oblique to the longitudinal axis. The measured peak dynamic coefficient of friction was 1.5, and the average dynamic coefficient of friction was 0.9+.
- Referring to Fig. 5, the tested average dynamic friction coefficients of various outsoles (including an outsole in accordance with the invention and other outsoles) having different.void-to-contact percentages are shown. Each "+" indicates the average coefficient for a particular sole pattern. The test involved weighting the outsole with a 120 lb. load and sliding it across a wet surface. The results reflect an average of five trials. The range of results among the five trials is represented by the shaded band. The highest dynamic friction coefficients occurred with void-to-contact percentages in the range of 10% to 40%, preferably 20%.
- Referring to Fig. 4, in other embodiments outsole 100 (for use by restaurant employees) has a tread pattern of
grooves 102. - In the toe area, there are six concentric arc-shaped grooves 102 (for men's size 10) centered on a
point 104 near the inside edge of the toe area. Adjacent arc-shaped grooves are separated by successively greater intervals at greater distances frompoint 104. Adjacent arc-shapedgrooves 102 are connected by shortstraight grooves 106 which are aligned on radii centered atpoint 104.Littleway groove 108 follows along the perimeter of outsole 10.Extensions 110 of some of the arc-shaped grooves, and of some of the short straight grooves, extend beyondLittleway groove 108 to the edge ofoutsole 110. - In the heel area are five arc-shaped
grooves 112 which are generally perpendicular to the longitudinal axis 114-ofoutsole 100 and extend from side to side in the region outlined byLittleway groove 108. Two of thegrooves 112 extend beyondLittleway groove 108 to the edge ofoutsole 100. -
Grooves extensions 110 are 0.090" deep v-shaped channels which form gaps of 0.110" in the bottom surface ofoutsole 100. Each channel has a bottom radius of 0.04" to 0.06". The side walls of each channel meet the bottom surface at an angle of 105°. -
Outsole 100 is molded of rubber having a durometer of 52-56 Shore A scale. - The pattern of
outsole 100 is particularly suitable in uses which require frequent rotational or swiveling motion around the ball area. - In one test of the coefficient of friction of an outsole like that of Fig. 4, a quarry tile surface, typical of restaurant floors, was flooded with water or with soapy water. With regular water, the average dynamic friction coefficient was over 1.0, and with soapy water about 0.95.
- Other embodiments are within the following claims. For example, referring to Fig. 6, a variety of other siping patterns can be used. The undulations of each cut can be more frequent (200) than in Fig. 1. The number of cuts on each friction bar can be more or less than three (200). The undulations can be relatively frequent waves superimposed on less frequent waves (202, 204, 206) and the orientations of the superimposed more frequent waves can either be coordinated with the longitudinal axis (206) or with the less frequent waves on which they are superimposed (202, 204).
- Other compounds (having different friction and other characteristics) and other hardness values can be used for the sole composition.
