Selecting the correct materials is critical, especially when contaminants are present.
By choosing the correct material, the maximum lifespan of footwear can be achieved.
- Nitrile rubber sole - for higher temperatures, l and solvent resistant.
- Polyurethane soles - for general purpose use, oil and solvent resistant.
- Anti-static footwear - to dissipate static electricity.
- Water repellent leather uppers - where there is an occasional exposure to water.
- Lorica uppers - where greater resistance to certain chemicals and oil is required.
- PVC, PVC nitrile, rubber and polyurethane uppers - where there is long term exposure to water and certain chemical applications.
- Cambrelle/Thinsulate/Thermalite linings - for greater comfort and temperature control of feet.
- Gore-tex, Sympatex and other waterproof membranes inside a leather upper - allow the feet to breathe whilst offering complete protection from water penetration.
If you're wondering whether the boots you have purchased provide you with the proper fit, ask yourself the following questions
- Q. Can you wiggle your toes? A. A little bit of room is good.
- Q. Do your toes press against the front of the boot when you're on a downward incline? A. They shouldn't
- Q. Does your heel stay in place when you walk around? A. It should
- Q. Do you feel any "hot spots" when you walk around? A. If so, they will more than likely get worse and cause blisters.
- Q. When the boot is comfortably laced, do the two rows of eyelets stay parallel to each other from your toes to your ankle? A. If not, it can mean you need a different width.
- Q. If you will be using the boots on rocky or uneven terrain, walk around and see if you can feel bumps and edges through the outsole. A. If you can, you will really feel them after a few miles on the trail.
Reviewing these questions will help you in deciding whether you have chosen the boot and fit that's right for you.
