  • HEXZORB‚technology - absorbs heel strike shock for daylong comfort.
  • SUPERDRI‚ lining - is hard wearing, wicks moister away from the wearers foot to prevent a sweaty and uncomfortable feel. It is fungus and rot proof so will not smell like cotton-lined boots.

  • COMFORT RATING - -20c to +20c.

The Bootie is lined with moisture wicking SUPER-DRI‚¢ terry knit, which keeps the wearer dry and has a super 100% stretch to fit most calves. As INSU-FOAM ULTRA‚ is a temperature Neutral material it will keep the wearers foot comfortable in a range of 85F to sub zero for a prolonged period.

TRAX‚ Sole, (DURAPRENE‚rubber) outsole withHEXZORB, which give superior grip on a variety of surfaces, the tread is designed to work with the action of the foot into zones for Grip, Traction, Stability and breaking.

Most GRUBSÆ Rubber footwear uses our self-insulatingINSU-FOAM ULTRA‚bootie construction which acts as a neutral medium between the wearer and the outside.The bootie is both waterproof and insulating and exceeds the long-term effectiveness of waterproof membranes and lofted insulations.Our boots are waterproof to EN ISO 20344: 2004 5.7 standard.

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 ourSUPER-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.

INSU-FOAM ULTRA‚is super soft and super bouncy, it has a compression set of less than 7% verses 20-25% for other neoprene boots, they remain soft and comfortable for much longer than our competitors. Other manufacturers use Styrene Butadiene Rubber, SBR, foams that are stiffer and harden over time, SBR also has a larger and more irregular bubble structure, boots made of this material are harder, making them uncomfortable and prone to leak through the bootie

Size guide ‚ We recommend purchasing the same size you are in your everyday comfortable footwear. If you are a half size we recommend sizing down as the boots have a 15mm allowance of a thicker, wool blend / combination sock.
