Warm, Dry, and Light
Thinsulate™ microfibers trap air without absorbing water, so 400 grams holds warmth even when the leather is soaked. Behind it, the sealed SCUBALINER™ keeps the water outside in the first place.
Why the Composite Toe Matters in Cold
Steel conducts heat away from your toes. On a sub-freezing site you feel it at the toe cap even through insulation — which is exactly where a composite toe earns its keep on an insulated boot.
Why Choose the CA3535?
A lightweight, insulated, waterproof composite-toe boot for cold, wet workdays — warm at the toe, and light on the foot.

Frequently Asked Questions
Is 400g the right amount of insulation for me?
400g is the sweet spot for cold, damp work where you keep moving, warm enough on a frozen morning, comfortable when the afternoon turns mild. If you spend long stretches standing still in hard cold, step up to the 800g CA3538. Insulation ratings assume your own movement supplies part of the heat, so an active job needs less than a stationary one.
Does the composite toe actually help in cold?
Yes, and this is where it matters most. Steel conducts heat away from your toes, so a steel-toe insulated boot goes cold at the cap first regardless of how much insulation sits behind it. Composite doesn't.
How long does the waterproofing last?
The SCUBALINER™ is a sealed membrane rather than a surface coating, so it doesn't wash off. Conditioning the leather and keeping the seams clean is what keeps it working over the life of the boot.
