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 FiveFingers comfort.

    I love this shoe. I have never.. never… loved a shoe like I love this shoe. For all you c….ts that ordered new vibrams when they went through the scientific issue about whether these shoes did or didnt work to strengthen the tendons and ligaments etc… you were caught up in a marketing war … but these shoes have been great. my feet are stronger (more prehensile even). I’ve thrown away all shoes that I don’t use for work. These are great shoes…. they should re-release them…. I will only wear KSO’s and I cant find them anywhere…. they are out of my size… so I’m doomed forever…. e-bay for me…. Why oh why won’t they re-release the simple black KSO. Did it last tooo long? Did it look too perfect? WHY???? …. Bring back the KSO people…. The Original … size 42 or 43 thanks If you can point me in the right direction….

      The new black KSO EVO has been receiving rave reviews Paladin, improvements to the sole design and ground feel, more breathable upper, better fitting upper, it’s a very nice upgrade and well worth a look. Unfortunately the original KSO has been discontinued and was last produced over a year ago. We are unaware of any available in your size globally.
