3 mm neoprene. Low boots that free up the ankles.
The seams of the boots are waterproof due to GBS assembly (Glued and Blind Stitched): the neoprene is glued and then stitched for maximum resistance (the needle does not go all the way through the neoprene to prevent water getting through).
Secures the fin/sole
Stop system on the heel keeps the fin strap in place so that you do not lose it when diving.
Neoprene booties with a more flexible vulcanised rubber sole.
The upper is reinforced to limit the discomfort of adjustable fins.
These scuba diving boots provide thermal protection that has been tested by the independent INPP institute (Marseille, France) in order to validate their compliance with the current standard (EN 14225-1:2017)
