• Footprint Kingfoam Elite Fluid X Orthotic Mid insoles are a mid-profile insole, slightly thicker than the low version, providing added protection and comfort
• With a bright green foam bottom layer and a woven black and teal top layer
• Adapting to each step utilising Footprint’s formula (the same that NASA uses!), reforms to your foot with each foot placement, giving you custom protection with each step
• Absorbs 91% of shock energy with shock absorption technology
• 5mm thickness throughout
• Fluid X Technology provides a custom-fit shape to your fit
• Nano Technology Energy Absorption is flexible when moving underfoot, but momentarily freezes under impact before transferring the energy, keeping you protected
• Body heat-activated, moulding begins once the insole warms up to your feet, or speed up the process with a home heat moulding method. Be sure to consult the packaging or the Footprint website for instructions
• TPU layer for firm Custom Orthotic and added resilience
• 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
