The main region includes forefoot area, heel area, and between forefoot area and heel area Middle section region.17 density of arc convex in variant region is different.In view of when walking, the concentration stress area of human foot is Forefoot area is concentrated in forefoot area and lays more close arc convex 17, is then loose arrangement to middle section transition Density, integral curved raised 17 distribution of heel area is loose, considers that heel position bears more gravity when standing, arc is convex Rise 17 laying it is also more loose, especially followed by middle section, arc convex 17 is almost without comfortable when wearing to guarantee Degree is laid entirely through the protrusion of each region different densities, on the one hand the abundant anti-slip effect of the guarantee main zone of action of power, and one Aspect is facilitated sweat guidance and air circulation, steam is accelerated to steam by forming groove 18 in the surface Nei Ren between each arc convex 17 Hair.

In the present embodiment, the highest point height of arc convex 17 is 1mm-2mm.The bottom surface of arc convex 17 is circle, bottom The diameter in face is 1.5mm-2mm.

The density of the arc convex 17 of forefoot area is 12-16/square centimeter.Heel area include followed by center and Followed by periphery, the middle section region and followed by the density of arc convex 17 of periphery be 6-8/square centimeter, followed by center The density of arc convex is 2-3/square centimeter.

It should be noted that (1) non-slip texture can be divided into linear by lines shape point and (continuously prolong in the utility model Curve, straight line, broken line, closed loop for stretching etc.) and scatterplot type (rule or irregular figure scattered or that concentrate arranged distribution).Press line Road distribution tightness degree point can be divided into uniform type (the entire region Nei Ren is uniformly distributed) and concentrated (is concentrated in main stress area It lays).

The product form and style of above-described embodiment and attached drawing and non-limiting the utility model, any technical field The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
