I have been using these. I don't think I have been using them long enough to give decent feedback but I can tell you what I know.
Jason doesn't know how long these last, he has had them on for months and they are still going strong so they last pretty well

Jason should be able to tell you how long he has had them.
As for performance. I can't really compare these to the old style hoofies as I have only used them briefly on other peoples stilts...that aside...I love them! I dont ever want to use anything else. The issue I was having with tire socks before was with them slipping and laces breaking and stuff like that...now these replace the hoofs so it is no different to having the normal hoofs on. For me, personally it's the best part of the design.
Onto grip and things. Again, I cant compare to hoofies but I did use tire socks before that were almost as good hoofies on some surfaces (but not all). To begin with the advise about wearing them in a bit to begin with is spot on. I was given the advise..yet first time using them was in the gym and I have to say that was a little silly. But anyway..I have been using these for a couple hours now over different surfaces and they are great all round. I can compare better to the normal hoofs. I think on normal hoofs the grip is good on a lot of surfaces but wears very fast.
All I can tell you at the mo is that they are deffo as good as normal hoofs but they don't seem to wear at all. Oh..and they are deffo better on grass.
I will give some better feedback when I have spent more time on them..been uber busy
