The Pearl Izumi 1:1 Insole system is a quality insole with forefoot and arch performance inserts designed to enhance both comfort and athletic performance at an amazingly low price. The insoles both increase comfort and help to align the leg for a more efficient pedaling action that correctly involves the proper leg muscles.
The system comes with two inserts for three Varus forefoot cant options - neutral +1.5mm, and +3mm. Also included are two arch support inserts for three options - low, mid and high. The inserts are simple to install/remove making the fit easy to dial in. Complete directions demonstrate how to use the arch supports and the forefoot shims for proper leg alignment.
