Abstract
Roller mounted shoe including at least one front roller (3a, 3b) and at least one rear roller (4a, 4b). The front (3a, 3b) and rear (4a, 4b) rollers are movable between a first ground-engaging position and a second raised position. The front (3a, 3b) and rear (4a, 4b) rollers are connected to one another by means of a flexible link (11) extending through the sole (2), so as to simultaneously displace the front (3a, 3b) and rear (4a, 4b) rollers using pull members connected to the flexible link (11).

- 34a, 34b) and rear rollers (4a, 4b;
- 35a, 35b) are interconnected by at least one flexible link (11, 26), so as to displace simultaneously the front rollers (3a, 3b;
