Description

A kind of sole with spring

Technical field

The utility model relates to footwear technical field, especially relates to a kind of sole with spring.

Background technology

Footwear are one of indispensable products during people live.The whether comfortable soft comfort level that is not only shoe-pad and upper of a shoe of the dress of footwear, also depends on the energy bounce-back of comfort level, the especially sole of sole greatly.Energy bounce-back value, namely energy rebound value, is a major criterion of weighing athletic shoe sole performance.So-called energy rebound value refers to: Sports shoe sole is after impacting ground, because its compressive deformation absorbs kinetic energy, before it is liftoff, can energy is discharged and return to wearer because of the recovery of shape, the percentage value that sole is returned to wearer's energy kinetic energy that shared sole absorbs be exactly energy rebound value.For improving the energy rebound value of sole, existing technological means is to add elasticity material or elastic structure at sole, yet easily there is lateral shift in these elastic structures, cause the stationarity of sole and wearing comfort not good in compressive deformation and the reciprocal process of bounce-back.
