Can "Chap leather" be used for boots?

I was looking on Maverick Leather, and they sell “Chap leather bundles” (4-6 oz) at a very reasonable price. 2 large sides for about $125.

Is the temper on this leather too soft for boots?

My experience with the cheap maverick hides has been they’re great options for prototyping things, but I have been disappointed with them all for trying to use for the “real” thing
