Custom insoles make everything better. They're in ski boots, running shoes, hiking boots, and just about every other kind of footwear out there, so why wouldn't they be in cycling shoes too That's the thought behind Giro's SuperNatural Footbed X Static Kit. Plenty of Giro shoes come with SuperNatural footbeds included, but if you have an older model, or want to update your current kick, it's the way to go. The trim to fit design means the SuperNatural will work with any shoe, Giro or not, and the small, medium, and large arch supports are easily swappable so you can figure out which size works best in different shoes. The insoles are made of EVA foam, which will compress gently to fit the shape of your foot, and have a super thin design that reduces stack height, which translates into increased power into the pedals. They're also finished with X Static antimicrobial fabric, so your shoes will smell fresh as daisies even after a summer of hard riding.
