Doubtful slippers on a foam sole. The soles look like they lack a firmer rubber. I suppose they wear out within a few miles unless your footprint is made of marshmallows. Shoelaces for the beauty as they really aren't needed. They remind me of water shoes. They are light, cool and comfortable but I think there will be no durability. UPDATE NOVEMBER 21: I added a star to these shoes. After wearing them for a while and even working with them outside, they actually held up better than I could have imagined. They're not very strong or durable, but they hold up pretty darn well for my use! I wish the laces were more adjustable as they could be tightened a bit. Although they are worth their money. 4 star purchase.
