Flex Back strap goes around the back of the foot, over the heel bulbs, and attaches to both sides of the boot with ball rivets. Back straps are available in three sizes and four colour options, so you can make your Flex Boots unique to you. Detailed instructions for correct fitting of the back straps are in our fit & size section, and a video tutorial can be found on our YouTube channel.
