Thickness: Approximately ⁷/₈" (2.2 Cm) in the sole and 2" (5.1 cm) at the highest part of the heel when used on most Wesco boots with the standard logger heel. Made of natural rubber. On the Motor Patrol and combat boots with the lower heel style, the heel is about 1.4" (3.7 cm) at its thickest point.

This is the classic Vibram lug sole. Used on logger, lineman and engineer fire boots. Hard to beat... but it does tend to leave scuff marks on floors. So listen to your mom and don't drag your feet.

Note: This sole does not leave scuff marks on phone poles, motorcycles or forests.

Non-Oil Resisting --- this does not mean that your soles will dissolve into a gooey mess if you step on some oil while parking your motorcycle. But, if you worked in a job where you were constantly standing in oil puddles, the soles would eventually soften and deteriorate. On the other hand, your toes wouldn't squeak.

When heated above it's temperature limit the #100 sole will slowly char.

Because it's made of a special synthetic rubber, it's a non-marking sole which won't leave black scuff marks on floors like the #100 sole does. It's flexible, slightly harder and slightly more springy than the standard #100 sole. It is also oil resistant. So this is a better sole for most uses, but it's more expensive. Boots made with this sole feel more cushioned than those made with the other sole options.

This #100R sole is available as an option on any custom Wesco boots where the #100 Vibram sole can be chosen.

This sole option costs an additional $6

• Heat Resistance - 475° F / 246° C for 40 minutes
• FIRE Resistance - Pass NFPA 5905

The research and development team at Quabaug Corporation developed this new Vibram^® FIRE compound. This unique, proprietary formula was developed to meet the needs of both structural (NFPA-Flame Resistance) and wildland (Thermal-Resisting) firefighting. The FIRE compound meets NFPA requirements for flame resistance and abrasion. In addition, this new compound provides a higher level of performance and durability.

The #100F soles are earmarked with a distinct red lug on the outsole.

This sole looks and feels about the same as the traditional #100 Vibram lug soles. It does leave some scuff marks on floors, but not much as the #100 soles do. This sole is standard on the Firestormer boots and is available as an option costing an additional $8 on all other boots.
