We use a super stretch Chloroprene material commonly used in Deep sea dry suits, this material has a 300% stretch and is covered with a 4 way stretch knitted nylon jersey which as suggested can expand not only in width but also height.  This super stretch means the bootie can stretch up to 150% as a laminate with our SUPER-DRI™, moisture wicking terry knit lining.  INSU-FOAM ULTRA™has a fine micro cellular structure, which stops heat transfer through its structure.  The microscopic bubbles of air are so small that it is waterproof even in 3.5mm thickness.
