These were huge on him. To keep the fake fur from felting and turning into a fused pad, it is best to avoid hot heat, yet if you do not dry them properly, the sponge sole will be wet. I am very pleased that I have found these. I have been having a pressure problem with my ear for awhile now and the doctors have no idea. Chose another slide by Adidas. Due to it pretty much being like a bubble gum machine bracelet at this point! The 300w amp is plenty of power to play the music loud enough while at cruising speeds! I accidentally wore them outside in the snow in freezing weather and didnt feel any cold. He chose this one and loves it. I AM PISSED AND I CANT BELIEVE THIS HAPPENED.
