When the norm is ice on your wetsuit hood and wind-chills below zero, the 8mm Custom Fire delivers tropical warmth and barefoot feel. The Fire starts with Solite’s new patented round-toe Thermo-Form sole which is 8mm thick in the toes, heel and underfoot and 7mm on the sides and top of the foot. The seamless sole is heat mouldable for a custom fit and sized slightly large to accommodate our 1mm neoprene Heat Booster Socks, which are included. The heat moulding process is easy and simple and can be done with nothing more than boiling water. The Fire offers 9mm insulation on the toes/underfoot/heel and 8mm on the sides and top of the foot.
