These are not the same as much less flexibility in the sole. Ive never felt like it was going to give away. 5 feet, so these were a little bit small at first because the inner part hadnt been worn in yet-I think it will be fine as I continue to wear them. Because of this when I wear it the bottom of the strap doesn?t actually touch my head at all and just sort of floats there. its definitely not waterproof. I?ve bought this same product from the store. No arch support, but still comfortable. This case is also very awesome at removing the slip on my AirPods case, which is one of the main reason I bought a case. Si alguien sabe donde puedo encontrar el codigo de activación de Razer 7. EDIT Jan 27, 2020I am amending this review after experiencing Oddicts customer service first hand.
