Ordered for my son. He loved the Levitation 2 but applied it in a decent amount of time. He does athletics. The next advancement was to get Levitation 4. They're already worn out. The toes have already gone through the forefoot and the sole is coming off. It hasn't even been a month. See photos. Very disappointed. Return and reorder Levitation 2. Don't buy Levitation 4 if you walk a lot.
