I will say they were supposed to fit all shapes of cross bars but the bottom attachment didn?t quite fit like I would like. I love this watch! So comfort wise I really like these. Its made from China what the hell do you expect a lot of fake crap comes from there it didnt pair with my PS3 and it did not pair with my PS4 beware listen to me do not buy this piece of s*** doggle USB stick it doesnt work Got these for my partner who really likes that they are true ?slip ons? ie don?t have an edge around the heel. The product looks great in the package, I loved all the attachments and it was small which I liked and made it easier to use. So all in all good enough value for the money. I work on my feet for 6 and 1/2 hours a day. I got this dress because I had a funeral to attend. The product quality is great and it is easy to use.
