First pair of barefoot shoes

It is my first pair of barefoot shoes and I love them. I can tell that a lot of research and testing has gone into these shoes and it shows; I appreciate all the little details, they do make the difference. All and all amazing quality. I have yet to properly test them in amphibious situations or in the water but on land, both walking and running, I'm very happy with them. I've always been athletic but with these shoes my calves and feet are quite sore just from walking fast, hopefully they will wake everything up properly. I have picked the wrong size but that's on me, I selected a size 40 when I should have gone for a 39 or a 38, I have looked at the JP cm measure next to the EU and UK size in other shoes I wear instead of measuring my feet. I have not sent them back though because the shoe fits really snug on my feet and there is no movement whatsoever even if I'm missing almost 1cm in front, with or without additional insoles also makes a difference. I was also incredibly excited to start the experiment so I could not bring myself to send them back. I'm keeping a log to track progress and working with a physiotherapist. I really look forward to keep the testing going and see what the results are in 3-4 months.

Belle e comode: quello che volevo!

Ottime, belle e leggere. Si adattano perfettamente al piede. Non le ho ancora provate in acqua ma hanno tutta l'aria di essere top anche lì.
