Size Chart The Nyord Furno 3mm Boot is built for surfers who want warmth and control without sacrificing board feel. The team have put these boots through their paces in UK winter waters along with the Edinburgh wave pool to ensure they give the standard of performance we are searching for while keeping your feet toasty. Many small features combine to elevate these boots to stand out from others on the market at this price. The minimal internal split toe is not too intrusive while you surf but stops your foot from rolling inside the boot, the o-ring and top strap deliver a drier boot and the smart “Halo” entry system makes them easier to get on and off while reinforcing the typical weak-point of many boots ensuring your Nyord boots will last longer. Designed and tested by surfers, this boot delivers a natural performance feel with just the right balance of warmth and sensitivity. The result is a very natural feeling that adds grip and performance while keeping the cold out.
