WATERPROOF 6.5mm Booties

The BI is a surprisingly light boot given the 6.5mm protection it offers. It has a substantial sole and is designed to seal to Waterproof wetsuit ankle seals on the W3 and W4 wetsuits.  This is a tough 6.5mm semi-dry boot with an extra long zipper for easy donning. The heels and toes are strengthened and the boot has an angled design for less stress while finning.
