Manufacturer: REXXAM Type: Data 93 Size: 27cm Since the 27cm and 27.5cm shells are the same, those who wear 27.5cm should also be able to use these without any problems. I gave these to my father (an instructor) as a present, but after skiing for one day (only two lift runs), he said he was tired and took a break. He never skied again, and they've been in storage ever since. They are almost new, so I would be happy if someone could use them. Ski boots these days can cost over 100,000 yen, so I think these are a good deal.
