FIELD: shoe industry. SUBSTANCE: shock-absorbing system has hermetically sealed chamber of elastic material filled with working fluid and placed inside heel cavity in spaced relation to cavity wall. Slots are formed in lower part of heel and side ribs are formed on lower part of chamber. When hermetically sealed chamber is located in heel cavity, side ribs come into contact with slots having smaller height as compared to chamber height for providing stable centered positioning of hermetically sealed chamber inside heel cavity. Such construction allows predetermined shock-absorbing extent to be provided for user at initial contacting of user's foot with support due to presence of shock-absorbing member in lower part of shoe.
