I needed a pair of casual shoes for exercise. I found them on sale for under $20 and my expectations were low given the cheap price. Dude when I received them I was skeptical at first but immediately I noticed the quality of the product as follows: 1. The seams are tightly sewn with breathable material 2. Memory foam soles sealed on the inside for maximum comfort3. no laces and wraps easily around the ankle by pulling on the tab on the tongue4. non-slip tread on the underside of the outsole for traction. I use them on the treadmill.5. Easy to clean and machine washable with warm water and no extra heat on the settings. Although I wish the profile was deeper. Extremely soft comfortable on my feet. I prefer these to my sandals for ease of use, looks and comfort. The product says for indoor use. I'm not sure how they are outside for running, but I go out and run errands in them and it's fine. Current prices are under $25, which is still good given that the average pair in stores is $30+ plus tax. Anyway, hope this helps and have a nice day. rob
