To be specific:- UI is terrible. Already sealed open and I have pay money as new phone My initial impressions were really good to say the least, with the explosions and enemy footsteps coming in with extreme detail. Love that it did that for me. Ive worn Tevas for years and these are as good as any with one exception the heel strap is none adjustable which is not a deal breaker as the fit is ok but would prefer to have the option. Give them a shot. Im one of those people who dont like going barefoot, and prefer some support or cushioning on my feet. First, great product! Im just wearing it in the house. you will lose them.
