Glued/sewn assembly
Neoprene 3 mm.
The liner's seams are waterproof, assembled using GBS (Glued and Blind Stitched): the neoprene is first glued, then sewn for maximum resistance (the needle does not go all the way through the neoprene to avoid water infiltration).
A latex sole is present: this increases walking comfort, resistance and therefore the longevity of the product.
Choosing the right size
Try them with your fins. The fit should be as snug as possible.
