This works really well. But most importantly he is able to put the sneaker on and take them off by himself. I?m very satisfied so far. These stay in, period. Didn?t have socks to go under soccer socks for her first game. 4a. I found a solution for around 40 dollars that would last around a year + and while they werent anywhere NEAR a full ear covering headphones quality they also didnt make my ears cringe. I;ve tried using without the little winglets but neither of the 3 size ear tips stay in, so need to use the winglets. Im not sure why the price for this is so high, but it does a decent job according to my yacht cleaner. They are easy to rinse out in the sink so I dont mind if they get muddy or filled with sand.
