You should be ready for any athletic adventure with this minimalist shoe. The KSO is highly popular among women for its unique versatility and lightweight feel. It features a thin, abrasion-resistant stretch polyamide mesh upper that encompasses your entire forefoot to “keep stuff out,” while allowing your foot to breathe. With a fit secured by a single hook-and-loop enclosure and a non-marking 3.5mm Vibram® TC1 performance razor-siped rubber outsole, your mobility is as unlimited as the terrain you are equipped to explore. The special grip allows you to stretch any surface – wet or dry.

Fitting Tips for FiveFingers Minimalist Barefoot Shoes:
KSO

With the single strap fully open, insert your foot while gradually aligning each toe with the appropriate toe pocket - it's often best to start with your big toe and work down to the little toe, gradually inching forward as each toe finds its place. Check to make sure one toe is in each pocket.

AFTER each toe is in place, pull up the heel cup and nestle your own heel into the FiveFingers heel cup. It's important to get your heel firmly seated in the heel cup.

Pull the single strap closure across your instep and secure. Make sure the strap lies flat as it wraps around the foot. Wiggle your toes and adjust the strap to find your ideal comfort.
