The Mares Classic NG boot are made using 5mm thick neoprene and offer a perfect balance between weight, thermal and abrasion protection. The size and shape of the boot have been designed to make sure the boots are get on and off but also ensure that they provide a snug and comfort fit. An anti-corrosive zip makes donning and doffing easier whilst the internal baffle prevents water ingress through the zip. The molded sole provides a comfortable, flexible protection from the tips of the toes to the heel with a raised section to keep the fin strap in place. Anti abrasion panels are fitted over the top of the foot to prolong the life of the boot but also to help the foot grip the fin pocket. Another anti-slip and anti-brasion panel if fitted over the heel to protect the neoprene from the fit strap and provide additional support. Please note: the size shown on the boots is the US sizing. If you opt for a UK 10 this will show the US size 11 on the boot.
