ITEM OF FOOTWEAR

摘要

An item of footwear for increasing leg-muscle and/or lower-abdominal-/back-muscle tone comprising: a securing means for securing the item of footwear to a foot of a user; and a sole comprising at least an upper layer, for engaging a foot of a user in use or a further upper layer, and a lower layer, for engaging the ground in use, wherein the upper layer comprises two or more materials of different compressive resistances, or densities, arranged as a frontal/toe region, an arch region and a heel region, the sole is arranged such that application of a user's weight, during use, causes instability in at least one portion of the upper layer, which requires balance correction by a user.

主权项

1. A method of moulding part of an insole or a sole of a shoe comprising:
(a) providing an arch region of first material of relatively lower compressive resistance or density; (b) providing a frontal/toe region and heel region of second material of relatively higher compressive resistance or density; and (c) placing the arch region between the frontal/toe region and the heel region within a mould; and (d) bonding the frontal/toe region, the arch region and the heel region together to form a unitary (in) sole having a wobble effect which, in use, requires balance correction by a user.
