All Grub’s footwear use our self-insulating INSU-FOAM ULTRA bootie construction which is super soft and super bouncy, with a compression set of less than 7% verses 20-25% for other neoprene boots, so they remain soft and comfortable for much longer. INSU-FOAM ULTRA has a fine micro cellular structure, which stops heat transfer through its structure. The bootie exceeds the long-term effectiveness of waterproof membranes and lofted insulations, such as GORE-TEX and 3M Thinsulate.
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. This means the bootie can stretch up to 150% as a laminate with our super dry, moisture wicking terry knit lining.
5.0 Technology has INSU-FOAM ULTRA bootie lined with moisture wicking terry knit, which keeps the wearer dry and has a super 100% stretch to fit most calves and will keep the wearer’s foot comfortable in a range of -10ºC to 30ºC (85ºF to sub zero) for a prolonged period.

Review by Mrs Henry
Excellent quality and very comfortable. I need to use Superfeet insoles and they fitted perfectly as I could remove the insoles supplied with the boots.
Review by Consumer
Ive only had the boots for a short while however Im very pleased with them. They are very comfortable and hard wearing. If I was to be honest they are not the prettiest of boots but they are very practical. Hopefully they will serve me well through the winter period.
Review by Arnold Chamove
Warm and comfortable but they only last a few (3) months with normal daily use. Then the tops crack where your foot flexes.
