[Question] how good are the nike machomai 2s?

So from what I've heard the problem with the nike machomais is that there is an arch on the inside (I still have an arched foot, dunno if that's a good thing or not in terms of boxing) and that it has no ankle support, how important is ankle support anyways or is it just a preference? And setting those aside how good of a boxing shoe is it overall? Thanks alot!
