GULL Mew Boots 3mm Size: 23cm Please be aware that there is a white adhesive-like substance on the toe area from the time of purchase. (Please check the last image with the red circle.) Used three times, so I think it's in very good condition, but it has been used, so I would like to sell it to someone who understands this. These boots were developed for Mew fins, providing a barefoot-like feel. ・The heel is made of jersey material for easy on and off. ・The angled shape conforms to the ankle angle during fin work, enabling smooth movement. ・Stretch jersey is used on the front part, dramatically improving ease of putting on/taking off and movement. 3mm neoprene, stretch jersey, SCS seal on the ankle Sole: 5mm
