* Footprint Gamechanger Elite Custom Orthotic Mid insoles are a revolutionary insole, ready to shake up what we used to from our insoles * Bright green underside with black and green upper * Thickness: 5mm Toe to 7mm Heel * Counteract the effects and help prevent over-pronation, giving you joint alignment support and also helping acute and chronic injury * Prevents arch collapse and gives relief from the effects of a dropped arch * Cradled Heel to disperse shock over a wider region * The moulding instruction is a must-read to feel the full benefits of these insoles * Trim down to fit your shoe size * Sizing: For a half-size, take a half-size up, for example, for a 9.5 UK, order a 10 UK * Fitting: It can take up to 5 days to break in the arch if you have flat feet. Although it can feel awkward at first if you have never had orthotics, once they fully break-in, you'll never want to go back to flat insoles
