A great shoe with a great sole of Vibram. While he ideally fit on his left foot, he was on the right way too small - a diversification in production? (No, sooo big differences in the lengths of my two feet there is not ...) The buyer may perhaps consider that the shoe upper in the heel leaves the feeling of not optimal grip with me and when existing problems with the Achilles tendon in turn exerts an unpleasant pressure at this point.
