About Vibram Soles
We're often asked what is the difference between the various choices in Vibram soles. Here is a quick overview of the main three soles we use on Viberg work boots.
Vibram 100 Lug Sole
The V100 lug sole (and the V1100 variant) has a strong tread and a block heel for traction and stability. The block heel makes this a good choice for climbing ladders and standing for long periods of time. The V100 sole is used on nailed styles, and is the standard choice for the 151X Contractor, 55VX Foreman Lug and 75X Lineman CSA boots. The lug sole is available in Oil-resistant or Fire & Ice versions.
Vibram 1276 Sierra Sole
The V1276 Sierra sole has an angled tread pattern and a rounded heel for stability on changing surfaces. This makes the Sierra sole a good choice for walking and hiking, or working on uneven terrain. The V1276 is used for stitchdown styles, and is the standard choice for the 45X Sierra, 148SX Rigger, 36X Bobcat, 40X Work Lite and 90SX Wellington CSA boots. The Sierra sole is also available in both Oil-resistant or Fire & Ice versions.
Vibram 700 Tygum Sole
The V700 Tygum sole has a smooth tread that is best suited for fashion styles. The Tygum sole is most often seen on the pull-on styles in our biker boot and western boot lines. There are two rarer CSA styles that offer a Tygum sole, they are the 51X Millwright, the 55X Foreman.
