A point of clarification. Vibram is not a material, Vibram is a brand. It’s an Italian rubber company that primarily makes rubber soles for many different manufacturers.
There are a number of Redwing boots that do use Vibram soles. The ‘supersole’ series of boots are the ones I use, they are the most oil,slip resistant soled boot redwing offers. ‘supersole’ is not made by Vibram. It’s a urethane sole. They are very grippy on hard surfaces, they are indeed very oil resistant. They lack deep texture so aren’t the best traction in mud and loose soil. They aren’t that great on ice. Urethane is more susceptible to tearing than other sole materials, so is generally not used for aggressive patterns. Urethane is very abrasion resistant, it takes much longer to where out urethane soles. I regularly replace the boots for reasons other than the soles.
My current hikers are Lowas. They use a Vibram, rubber sole. They offer very good grip on outdoor surfaces, mud gravel, asphalt, snow, ice. They are not very good on tile or other finished surfaces. Getting oil on them turns them to ice skates. They are softer and wear faster. My primary reason for replacing hikers is the soles wearing out.
