It is almost time for me to buy new boots.
I have become seriously disappointed in the soles available.
New Vibram wears longer because it is much harder than it used to be, but it sacrifices grip for resistance to wear.

Natural rubber and crepe rubber give excellent grip but wear out and get eaten up by oil too fast.
Felt soles and caulked soles are great for what they are meant for but are not what I need.

Has anybody found anything with really good grip even on wet steel that wears well?
