When I first bought a tab of this material I thought it was synthetic. It shows almost no wear, I still have the first tab I bought and it is well broke in and great for low weight target bows. Then after I had it for more than a year I was looking at it closely on the back of the cordovan and I saw part of the stamp and realized it was some kind of premium leather. You could have knocked me over with a feather. I still don't know if you can wear one out. I have a glove with cordovan on the finger tips, and three tabs, two of which are still new. I like to use the new ones on heavy bows, and the glove works well on heavy stuff as well.
The horween web site is a good read, man I would like to have a pair of boots made out of this stuff. The only trouble would be breaking them in and finding soles that would last anywhere near as long. Good stuff.
