It helps a lot for traction, and honestly, way less slippery than dianites.
That's been my experience, as well, both on my feet and in shoes I've made for others.
But Rendenbch and Baker aren't the only good tannages.
Baker is exceptional and pure oak bark. That said, they seem a little soft (to my taste). The insole shoulders are without peer however.
Rendenbach is very good and mostly valona (acorn caps) tanned but too brittle for my druthers.
I've taken to using a Belgian chestnut tannage from Manseur (sp?) that is beautifully coloured, finishes up just as nicely and is"just right" in terms of temper. And best of all available here in the US...without a brand on the grain surface.
Parenthetically...and I've said this before...some of the "slippery" issues with any soling material is the way a person walks and where they carry their weight. Ask any fly fisherman who wades dangerous rivers, if you don't have your weight squarely over your feet before settling on them you're in for a dunking. That said, I've actually had moments when I thought...esp. in very cold weather...that if you walk slowly and deliberately, good leather outsoles are superior to any rubber on ice. Stick your tongue on a patch of cold ice and you'll know why.
