The Grubs FROSTLINE 5.0 Boots are insulated and suitable for sustained periods in temperatures down to -10 degrees centigrade. The Grubs FROSTLINE 5.0 Boot has a TRAX sole pattern, with small lugs front & rear to provide a good 'push off' grip and a prominent heel for a 'braking' grip.
The footbed of the Grubs FROSTLINE Wellington Boots has a 6mm Nitrocell providing both insulation & cushioning, promising you a comfortable and lightweight outdoor boot that you will love. For a more durable and hard-wearing boot, the foot and lower calf area of this boot has a 2mm thick layer of tough rubber. This rubber layer protects against damage by brambles etc.
Features:
5MM INSU-FOAM ULTRA - gives all-round foot comfort and insulation.
6mm NITROCELL foot bed - provides a soft cushioning for an athletic shoe feel. A million microscopic nitrogen bubbles insulate the wearer from cold surfaces.
UNDERFOOT CHASSIS - give a sure-footed platform.
HEXZORB technology - absorbs heel strike shock for daylong comfort.
SUPERDRI lining - is hard-wearing, wicks moister away from the wearer’s foot to prevent a sweaty and uncomfortable feel. It is fungus and rot proof so it will not smell like cotton-lined boots.
TRAX out sole - superior grip on a variety of surfaces, the tread is designed to work with the action of the foot
COMFORT RATING - -20ºc to +20ºc.
INSU-FOAM ULTRA™
Most GRUBS® Rubber footwear uses our self-insulating INSU-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 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. INSU-FOAM ULTRA™is super soft and super bouncy, it has a compression set of less than 7% versus 20-25% for other neoprene boots, and 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.
TRAX™ Sole, (DURAPRENE™rubber) outsole with HEXZORB™, which gives 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.

Please note that our Wellington Boots have a 15mm allowance for wool blend/combination socks.
With this in mind, we would recommend purchasing the same size you are in your everyday comfortable footwear.
For half-sizing due to the allowance, we would recommend sizing down.
