First one I ordered didnt work and they were very helpful in getting my a new corrected charging devic for my Bose speaker Supposed to be uk size 10 however even with thick socks are not uk 10 one shoe seems to be stretchedComfy shoes but too large compared to my other sketcher shoes uk 10 and sketcher trainers size 10Also shoes show white Marks all over them and difficult to cleanNot worth the money I paid really dissatisfied with product Overall they are comfortable and the one speaker that works is great but very disappointed that these came broken. If you?re reading these reviews and you?re a little worried about ordering the product because you saw where some people said that their phone went flying off of the handle bars, know this: When I first mounted it, yes, the ball and socket would easily pull apart and did give me a false sense of security but you HAVE to get it tight so the socket properly grips the ball mount. Muy lindas y comodas; llegaron en el tiempo previsto, en su caja; sin embargo tenia pensado utilizarlas como sandalias de baño, pero por el material con que están hechas es muy tardado que sequen ! This does exactly what I needed it to do. Definitely recommend this product! She reports they fit perfectly and were immediately comfortable.
