TERRIBLE CUSTOMER SERVICE - TERRIBLE PRODUCT. (1000kg). He wears these almost every day, and theres no redness, blistering, swelling or lace rash marks. Fit great. It has the right amount of extra buttons. I used this to build an entire road bike. Perfect Flip Flop and perfect day shoe for Florida! Its a sad fact that todays kids need more stimulation to keep their attention. No recomiendo que se mojen porque la parte de arriba trae foam. The sound quality is great these fit perfectly in my ears no pain at all I even fell asleep with them in and they were fine.
