Great shoes, came with box. Brand new, true to size 11 US ! :) in my country they cost 270 USD so, really nice and very comfortable shoe considering i have plantar fasciitis. 3 month update: They get wrinkles pretty fast in just a few weeks due to the material, it’s not noticeable to others at all, but it’s worth keeping this in mind when buying this particular model.
