It's a very good product, no doubt on it. I gave 4 starts because I felt some discomfort while walking. Not that much to worry about, but you'll feel it.
It's super. Model and shapes appear. They are also very soft. Weight is less. It's fine. But it is not waterproof and the sides are glued with so much gum that it will blow away if it gets wet. It would have been better if it was water proof.
