You can hear every little thing. Ive gone through a lot of other shoes that I bought and couldnt wear for more than a couple minutes. Cons:The Keens rubber toe is more substantial. The size is correct, and fits well. :-DWorth the money and recommend you buy a pair. Cant speak on the long term effects just yet but it definitely makes you sweat which is exactly what its intended for. The only thing I?d like to change about it is a tiny bit more strap. The foot bed is soft, yet sturdy and substantial. I looked up Muk Luks again and was worried that something may have changed - NOPE! They look cute but not comfortable.
