From the mouth of my 10 year old. "They are comfy and they feel like you are walking on clouds". They seem very soft and I don't think they will cause blisters. My only concern, and why I gave it 4 stars, is that they don't have much traction on the soles and I am pretty sure it would be slippery on a wet tile floor like in a bathroom at a restaurant or store. Only time will tell. I will let my daughter field test them a bit longer before I purchase a pair for myself.
