text: I bought these thinking they'd be good for an upcoming vacation that will involve a lot of walking. Good thing I tried them out at home first. The memory foam is super comfy, but I can't say the same for the rest of the shoe. The back rubbed against the back of my heel in a really uncomfortable way, despite the fact that I was wearing socks. I only wore them around the office, but by mid-day I was putting bandaids on my heels to prevent blisters. Heel grips might make these tolerable, but come on. Comfort-focused sneakers shouldn't require heel grips.
