I guess it?s the cloud foam but it?s super nice. I was not happy with the stand, and ended up returning it to purchase a DR Pro, which was WELL worth the extra couple bucks. Added bonus: I did not know that they light up! I had a look in mind these these came up. It?s much less flimsy and feels like an Arctis Pro (which I have also owned). They just broke and I?m upset I want my money back. Di contro devo dire che non va bene per le scarpe di un adulto e che trovo il prezzo un po? caro trattandosi di plastica. Even though I bought a size bigger it looks fit somewhat small but it still fits me. Was really disappointed for I was looking forward to its usefulness. These fit like a thick sole flip flop from a big box store.
