I am now wearing Ariat Performers and Ariat half chaps. These are
the best boots I've ridden in and my foot no longer "slides around" in the
stirrup. They are also holding up really well(All the others were dead in 2
months).
As for stirrups-I like them thinner. The only time my feet get numb
is if I'm posting from the stirrup and not through my whole leg.
Just my experience and opinion.
