The Drylock 5mm split toe wetsuit booties from Xcel Wetsuits have a new, thinner sole design for a better feel with your board. Xcel also redesigned the Velcro straps to be at an angle for improved comfort and fit.
All Drylock boots are 100% blindstitched, which means a more watertight construction since no stitching fully penetrates through the neoprene.
Took these out about a week ago - never owned a 5mm before - couldn't believe how warm they were - my feet never got cold in a 2 hour session. Very good quality - I've owned XCel's before - they last a remarkably long time, (I've tried different brands too, and XCel's are the best in my opinion). I'm a fan of the strap over the foot, it allows you to make them as snug as you want. Highly recommended.
