If your feet are cold then the rest of your body doesn’t feel comfortable at all. If your bots aren’t insulated then your feet especially your toes become vulnerable to many complications some of which are frostbite and circulatory issues. Insulation actually saves your feet by maintaining appropriate temperature.

It creates a barrier against cold and dampness and preserves warmth and maintains blood flow. Therefore insulation plays a major role in keeping your feet healthy while you work in extreme temperatures.

What is Thinsulate?

Thinsulate is basically a fabric which is manufactured using synthetic fibres woven together to make various layers of certain thickness so that it can keep your feet warm at a range of temperatures.

This thickness is expressed in grams per square metre or simply ‘GSM’. Basically, Thinsulate ranges from 40 gsm to 800 gsm.

GSM and protection are inversely proportional to each other. That means, the lower the GSM, the lesser protection your boot will offer in cold conditions. Boots with higher GSM have the tendency to keep your feet warm and protected even in sub-zero condition.

However, it sometimes might become a bit uncomfortable because of thicker fabric. Thinsulate are available in different weights and before purchasing one, you should always consider these factors.

      • The temperature and environment in which you’d be working.
      • The amount of fine or large motor skill activity.
      • Insulation at the toes
      • The manufacturer of the boots.
