I rely on the dimensions in the product description, for each size is there the number of centimeters sole stated. Gr. 39 has, according to Table 24.00 cm. The shoe came and was much too big. Sole length 25,5 cm! That makes for a Gym.schuh from an awful lot that needs to fit perfectly so. For me, now totally annoying because I have to change and has to get involved in a new "size gambling". Because ansich the shoe is really good, thick soft padded insole, very soft leather, good workmanship and comfortable fit. Not quite as slippery as are covered by the sole only small parts with rubber if they offer good adhesion I do not know z. B. on the balance beam. I would definitely recommend shoes but just the size I would advise to contact the seller and, if his foot measurements by adding as you go to the specified in the product description below degree can not rely as I said. Because the return shipment have to pay yourself, you get no return label from Amazon!
