The Grubs Railine is better than ever before. It features a TRAX sole which makes for a better grip and provides excellent stability on the waterfront. They consist of a rubber foot (with the reinforcement at the level of the teentop, Achilles tendon, and tibia), a shaft in chloroprene and a jersey lining of 5.0 mm thick, which means that the boot is suitable for prolonged periods of time within the specified temperature range.

Grubs 5.0 Technology

All Grubs footwear uses self-insulating INSU-FOAM ULTRA bootie construction which acts as a neutral medium between the wearer and the outside.

This unique super stretch material is commonly used in deep sea dry suits, and has a 300% stretch rating. It is then covered with a 4 way stretch knitted nylon jersey which as suggested can expand not only in width but also height.

In our 5.0 TECHNOLOGY™ boots the bootie is lined with moisture wicking terry knit, which keeps the wearer dry and has a super stretch to fit most calves. As INSU-FOAM ULTRA™ is a temperature neutral material it will keep the wearers foot comfortable in most conditions for a prolonged period.
