The Chippewa 8 inch waterproof insulated aluminum toe Norwegian Welt Polar 90 is made of tipped briar leather with a Norwegian leather welt construction. This boot also has a Chip-A-Tex waterproof bootie and an insulated removable orthotic insert with a Vibram Bighorn outsole. The safety toe is ASTM F2413-05 approved aluminum toe and is electrical hazard rated.
|Vibram Gumlite is a micro-cellular, synthetic compound that combines slip-resistance with the long-wearing characteristics of rubber, yet Gumlite is half the weight.
|35% Lighter than steel toe caps, No heat or cold temperature transference, Non electrical conduction or magnetic charge, No rusting or corrosion, Meets or Exceeds ASTM F2413-05 Standards For impact and Compression.
|Non electrical conduction of electrical potential or magnetic charges. Safety toe cap meets or exceeds ASTM F2413-05 standards for impact and compression.
||The Chip-A-Tex waterproof membrane system is breathable. Water is locked out of the boot by the membrane shield but air passes through from the foot for maximum comfort.
|Just like regular Thinsulate, it is lightweight, breathable and moisture-resistant. But Thinsulate Ultra insulation goes one step further. It is loftier and thicker than original Thinsulate insulation-for even greater warmth and comfort, yet still thin enough to allow complete freedom of movement.
