The MT580 might be the oddest out of popular New Balance designs. It's a take on the original 580, but made for Japanese consumers. The sneaker's massive amount of stability causes it to have such a chunky midsole, but still won over fans with its not-so-sleek looks. It's like the chubby kid who can get laid. Americans were finally lucky enough to have the MT580 spread over to U.S. releases, although tracking down the earlier Japanese editions is near impossible.
