I recently purchased these and wore them surfing once, but they were a bit too snug for my feet, so I'm reluctantly selling them. My usual shoe size is 25.5cm-26.0cm, and these are size 26cm. I think they would be a good fit for someone with 25cm feet or someone with 26cm feet who have narrow feet. Purchased for around 7500 yen. Neoprene material with a thermal inner lining (brushed, warm, cold protection, fleece-lined, dry, quick-drying) 26cm black boots Split-toe inside Non-slip sole Perfect for marine sports - Size: 26cm - Color: Black - Material: Neoprene + thermal inner lining - Sole: Non-slip Thank you for looking.
