Those with very narrow feet may find that their feet slide from side to side in kyBoot.
We have volume adjusters (Filler insole) available. These usually fix the sideways sliding, but can cause the heels to slide up at the back.
SOLUTION: The volume adjusters in kyBoot mean you are higher up in the shoe, which can mean that your heels tend to slide up, depending on their shape. We recommend lacing up your kyBoot firmly from the very bottom to the top. You may possibly need smaller-sized kyBoot.
