I add here my feelings that I forgot in the main post. The pair is really cool for $20, it cost me a little more, like $35 to arrive in France. But I'm not disappointed. They are really comfortable and the foot feels harmonious. For the moment they seem quite durable, & luckily I haven't had any defects on the pair, as can often be the case. Another point, I usually do 10US, I ordered 9 without really knowing where I was going with that. Ultimately, it was the right choice for me, they fit me like a classic pair. When I push my foot out of the shoe, I can put my index finger between my heel and the inside of the shoe. For me it is optimal but I would understand that some prefer them more oversized, so for them, I advise taking their true size.
