Neoprene diving boots with straps for an excellent fit. Size: 23.0 - Brand: BLUE ACE - Color: Black/Red - Type: Diving Boots - Features: With Straps - Material: Neoprene Purchased two years ago and used 1-2 times in a river, then stored in a shoe box. I usually wear shoes size 23.5-24.5, but I think these boots fit perfectly without feeling tight. There are no noticeable stains, scratches, or tears. The Velcro is also functioning properly.
