Super comfy "slip on" type of sneakers. Cushioning on these are great as you really feel like you're walking on pillows. I've had them before but sadly they're being discontinued. These are a great everyday sneaker to wear though I wouldn't run in them seriously as I find my feet sliding around inside a bit too much. The sole though soft does wear out fast which is the only real negative I can find on it. The upper mesh is very breathable and flexible though not very durable. If you fall and rub the shoe on the ground, it could likely leave a hole in it like an older pair of these did for me.This shoe is barely a shoe. It felt like I was wearing a reinforced quilt. I had no confidence that this shoe is going to hold up to any sort of wear and tear so I sent them back.When I called SneakersRX to return them they told me I had to pay the return shipping! It took almost a week for the shoes to arrive in the first place and now I have to pay to return them? I am extremely perturbed about this. I have order from Zappos many times and my shoes typically arrive next day with a prepaid return label.Once again Amazon, you've given my business to another horrible third party merchant. When will they realize that, by doing business with these vendors that offer horrible service, the Amazon brand suffers too?Oh well. Zappos, here I come. Oh, how I've missed you!lightweight and awesome
