Just the weight of the Kayak being pushed from the wind managed to sheer one of the bolts and bend the frame. Offered them to my daughter who wears 7. Easy install with 4 screws each section that were included. Very comfortable, but will have to apply vaseline or slick hair shine serum between the top crisscross pieces, & on each side of the inside of the shoe where the straps are connected to each side of the shoe. The locking feature is great as I can leave the rack on the hitch with confidence even when we are not transporting our bikes. Will update this review after about a week or so once Ive had a chance to actually test their performance. I feel like I won with this transaction! Overall: For 40/50 bucks, these are excellent. Junk do not buy. the light toggles purple either way.
