ABSTRACT:
The invention relates a sport shoe having a shell base topped by an upper that is pivotal/flexible with respect to the shell base via a flexion control arrangement. The flexion control arrangement includes a viscous element interposed between mobile portions which overlap and displace relatively with respect to each other when the upper pivots, forming a flexion control by viscous friction. The viscous element procures a silent and constant braking between the mobile portions.
