Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing:

As shown in Figs. 1-5, the present embodiment provides a kind of damping improved soles, including outsole body 100 and compound abaculus 200, the compound abaculus 200 is by EVA elastic piece 10 and the TPU stabilization 20 being inlaid in inside EVA elastic piece 10, the TPU The horizontal middle part for being flush-mounted in EVA elastic piece 10 of stabilization 20.

In the present embodiment, the rear heel top surface of the outsole body 100 is recessed with accommodating cavity 101, the accommodating cavity 101 Open top simultaneously has step 102, and the compound adaptation of abaculus 200 sticks in accommodating cavity 101 and the TPU stabilization 20 The corresponding support cooperation of periphery on step 102, the deformation downwards of TPU stabilization 20 can avoid excessively by step 102, also favorably In the compression strength and support strength that guarantee the compound abaculus 200 of the present embodiment.Wherein, the TPU stabilization 20 with a thickness of 2mm ~3mm.

In the present embodiment, it is spaced apart from each other and is disposed with before and after 10 bottom surface of EVA elastic piece abutted against with 101 bottom wall of accommodating cavity First support bar 30 and the second support bar 40, first support bar 30 and the second support bar 40 are same with EVA elastic piece 10 respectively One material is integrally formed, and is respectively kept with interval between first support bar 30 and the second adjacent support bar 40, the interval is wide Degree is 2mm~4mm.There is first support bar 30 spaced three the first convex blocks 31 in left and right and arc-shaped transition to connect phase First concave surface 32 of adjacent two first convex blocks 31, second support bar 40 have spaced three the second concave surfaces 42 in left and right and Arc-shaped transition connects the second convex block 41 of adjacent two second concave surface 42,41 correspondence of first concave surface 32 and the second convex block, 31 correspondence of second concave surface 42 and the first convex block, left and right sides of the first convex block of two of them 31 respectively close to EVA elastic piece 10 Edge, left and right side edge of the second concave surface of two of them 42 respectively close to EVA elastic piece 10, the first concave surface 32 and the second concave surface 43 It is respectively formed the bradyseism recessed area that opposite first convex block, 31 tread surface or 41 tread surface of the second convex block are recessed upwards, is effectively improved Compressive deformation ability and enhancing buffering and damping effect of the sole at this.
