The back strap goes around the back of the foot, over the heel bulbs and attaches to both sides of the boot with ball rivets. All Flex Boots come with back straps as standard, but you can also buy the straps separately if you need to replace a broken strap.


Back strap sizes are:

Small = 10" long

Medium - 11 3/4 long

Large = 12 1/2 long


If replacing a broken strap, please check if your ball rivets are intact, or whether you need to order new ball rivets also. All replacement parts for Flex Boots are available in our online store.
