This is my first pair of Vivobarefoot...I love these shoes!! Better than expected with the fit and coloring! Read many posts before buying regarding the euro sizing and even researched on Vivobarefoot website to review sizes and comments. I wear a size 8.5 and wanted to make sure I wasn't ordering too big or too small...the Euro 39 worked for me - on the Vivobarefoot site it shows Euro 39 as an 8-8.5 not 8.5-9 as shown hear - fit perfectly!! Looking to buy another pair before the price goes back up to $110!
