The split toe design allows the foot to spread naturally, preventing roll and giving maximum grip and feel. The split toe end is covered with flexible rubber to stop the leash getting caught up.

The boots have an arch strap and a pull tab on the back to help get them on and off in the cold. They also run a decent way up the leg to guarantee a good overlap with the wetsuit.
All in all a top of the line boot.

Size Guide

The boots will feel quite tight at your normal shoe size, but a snug fit it important.  However, like all neoprane, they will stretch and loosen a little over time.
