Abstract (en)
[origin: WO9318677A1] In a shoe sole (2) comprising a first chamber (6) and a second chamber (7), which chambers are completely or partially filled with a fluid (10), and a channel (11) interconnecting said chambers (6, 7), by means of which channel the fluid (10) upon compression of one of the chambers (6 or 7) may be transferred to the other one of said chambers to expand said other chamber, the first chamber (6) is positioned so as to extend essentially only underneath the heel portion (8) of the foot (5) whereas the second chamber (7) is positioned so as to extend essentially only underneath the longitudinal arch (9) of the foot (5). Upon expansion of the second chamber (7) due to the compression of the first chamber (6) when affected by the heel portion (8), said second chamber forms a dynamic pronation support underneath the longitudinal arch (9). When this arch bears a weight thereon, it causes the second chamber (7) to be compressed.
