Talla correcta y modelo correcgo aunq pense que eran originales de adidas perono lo son I have arthritis in my left foot, and it swells. Bottom - not so much. Great product quality, spacious and easy to carry. This product was just okay. Got this as my phone is thin and was hard to grip for me as I have arthritis. The sound they create is awesome, deeper bass and a snug fit = jammin workout Mount it on the new wood either as close as possible to one stud, or even better, two screws on on stud, the others in your new support. They are really nice. Would have been nice if that were a different material.
