1523971 Sandals SCHOLL (UK) Ltd 16 Jan 1976 [17 Jan 1975 22 March 1975] 01831/76 Heading A3B A foot exercise sandal comprises a sole 1 whose upper surface includes a ridge 3 extending in use, under the arches of at least the second to fourth toes, increasing in height to the second toe and dropping downwardly, at 4, in the region of the big and second toes to merge into a depression 5 for the ball of the big toe and a flattened portion for the toe, the sole upper surface being held in engagement with the sole of a wearer's foot by a strap 7 over the wearer's instep. The ridge 3 preferably extends from the outer side of the sole i.e. the little toe side and the downwardly extending portion 4 of the ridge may be at the outer face of the big toe, at the inner face of the second toe or between these toes. The ridge may become broader towards the portion 4. In one form, Fig. 3 the portion 4 is inclined to the vertical from its upper end to the flattened portion and in another form, Fig. 5 (not shown) the portion 4 has a rounded upper end which merges into a groove (4') at its lower end which slightly undercuts the ridge and merges with the depression 5. A shallow depression is preferably provided in front of the ridge 3 for the ends of the toes and a shallow heel depression and an arch corresponding to the foot arch are provided. The sole 1 is substantially rigid, is preferably of one piece and may have a heel. There is a covering 6 on the sole lower face to the bottom surface of which a coating e.g. non slip material may be applied. All or part of the sole upper face may carry a resilient layer. The strap 7 is positioned behind the ridge 3 and may be of two pieces, as shown, secured together by a buckle or press studs and may be permanently screwed or nailed to the sole or may be changeable for a different strap, then fixed by press studs to the sole.
