Theyre a very light wood, but feel sturdy enough to hold up to everyday wear. The only issue I had was when the straps got wet they would start to irritate the back of my heel. I?m happy that I get to charge my AirPods wirelessly. Note to self:Pay attention to the reviews. It also pinched on the skin multiple times causing minor bleeds. El pincel es bueno ,el color la presentación bonita. My apple Airpods started hurting my ear so I purchased these after a friend recommended it. but these i do not mind at all! A bit expensive for flip flops, but if these last half that time, they?ll be worth the money. Keep in mind these shoes have absolutely no arch support.
