as first put the shoes on it felt really tight i cant even wearing sock with X4 which X3 confident to did , i thought maybe it was an defective on my shoes but as your confirmed i think it may come from Reebok change the way it fit. other than that im really happy with the Miami colorway.
I bought a 12 and a 12.5,just in case. For me, the half size up wasn't really needed, they are quite comfortable tts, more so than the 13, and I thought the 13s were just fine
DO NOT WASTE YOUR MONEY!Used new nano x4 four times and while thigtening the shoe shoelase riped the hole open. Reebok offered promotional code for the next order 😂. Who wants to use more money on product with no quality
