I bought these shoes because of my job, which requires standing for 5-8 hours daily. From the first few seconds, I noticed the difference! (I used shoes with air soles and my feet still hurt). Immediately, the memory foam made the sensation softer and the fatigue weaker. I couldn't believe it when I read that they do the job, especially for shoes that cost 45€. The only negative thing is that they are a bit harder on the heels. For anyone who has to stand at work, I recommend them, don't think twice, get them! Update: After 1 month of use, I can't say that I feel the same relief. The foam has "settled". It's a bit like wood. However, for 45€, which is what I bought them for, they are still worth it, although I would choose something a bit more expensive/better
