The Hubboards 2mm Neoprene Bootie with Sock Lock. Hubboard's revolutionary fin bootie uses a super comfortable 2mm neoprene that is cut and flat lock stitched into a full length high, foot shaped bootie that fits your foot perfectly. Their New Sock Lock technology is a built in fin tether on your bootie. Their revolutionary design will give you a fin tether and bootie, all in one.  The sock lock works by buckling the tether on the outside of your fin strap. This design allows the fin to be locked to your foot so that you do not have to worry about losing your swim fin or bootie ever again.
