A sole for a shoe is disclosed which includes a resilient mid-sole (14) in which first and second flexible containers (18) are inset at the heel and forefoot regions of the sole. The containers are filled with a fluid which provides a cushioning medium and a connecting tube (19) provides a balancing of fluid pressure between the containers (19) as well as cushioning along the pressure path of the foot on the outside edge thereof. The embodiment of the invention also provides a valve formed by ribbed members (16) which constrict tube (19) when pressure is applied to them to trap increase in fluid pressure transferred into the forefoot container on initial heel impact to give an extra platform of resistance under the forefoot for a better push-off and "kick". |
