Shipping & Returns

Designed to refine the fit, this premium insert sits between the insole and sole to subtly reduce interior volume—ideal for slimmer feet that need a more secure feel. Crafted for added thickness without sacrificing comfort, it helps prevent heel slippage and enhances stability. Compatible with all Koio styles built on our Capri construction: Capri, Garda, Portofino, Primo, and Capri Mid.
