Put your best foot forward in every situation. These insoles are ideal for narrower shoes with lower profiles and less volume (such as dress shoes and form fitting styles). The ET75 features a specialized, slim-profile shape designed to improve alignment and pressure distribution, so you can feel as good as you look. Without the additional shock absorption foam layer in the heel, this insole will sit flush with the shape of your shoe. Let ET75 help you succeed, whether you find yourself in an executive office or on the dance floor. These insoles are a ¾ size, made to fit on top of an existing insole. Whether you are constantly on the move or if you simply need a little more support, experience your world and do what you love, in alignment, with Protalus.
