It is sturdy, and gets the job done really well. 5 mexicano pero la comodidad y lo calientito supera el hecho de que me quedarán un poco justas, es una excelente marca Bought for my son who is 14. It is so easy, it kind of makes you look like a show off, while others are struggling to secure their SUP! Gave my daughter blisters on her ankles and arches the first day she wore them. Not the most comfortable but they seem like decent quality. But sure enough the big kid 5 is too big and the big kid 4 is big but doable. I?d be fumbling trying to get them plugged back in. Buying this device for the mic makes you incompetent. Enjoy my hundred bucks I guess :/
