Selling because I want to change my system. I bought a larger size, but I've adjusted it tightly with the laces, so it should fit comfortably for people with 27.5cm feet or smaller. The condition is that the surface is clean, but there's some sand on the sides of the soles, and the soles have a cracked pattern. I've done some light self-repairs, so I think they can still be used. Those who are sensitive to such things should refrain from purchasing. I'm considering lowering the price due to the dirt, so I'll consider offers. Please purchase only if you agree with the condition. No returns or exchanges (NCNR).
