I ordered a size 39 shoe from this company. The shows are not size 39 - they're a 38 at most. I can barely get my feet into them. When you leave a review or ask them a question about it they say you should check the size guide. They know these shoes are too small and won't make it clear that you should definitely order at least one size up. If not two. I think a size 40 in these might still be too small for me. I measured the shoes - they say on the size guide that the length is 249mm. A standard size 39 instep is 246mm. So you would think its ok. The 249mm is not the instep. It's the absolute maximum length of the sole include the bits that stick at out the toe and heel. This company will respond to bad reviews - they are only concerned about social media - they do not have good quality control.
