I ordered these on a whim because I was looking for some lightweight slippers and they didn't disappoint! Very comfortable, super light and I love the low cut around the ankle with the higher heel counter. I wear them closed toe due to my low ankle and have had no issues with the back of the shoe pulling them down or chafing my ankle/tendon too much. I'm not a runner so can't condone this use, but I do long walks (8+ miles) a few times a week and they've held up great with no complaints. I used to buy pull up shoe inserts (I stomp a bit) but there was no heel discomfort in these shoes with their original insoles. They're definitely not waterproof either, and the mesh material on the top has some dirt from running on a rainy day. They clean great but I wouldn't recommend wearing them regularly in a wet environment. I am only taking off one star because one of the laces was quite worn when it arrived. I ended up buying elastic shoelaces to replace them (and make these slip-ons) and they are now my go-to shoe for most purposes. I've had them for about a month and I really don't see any wear on them yet. Very satisfied!
