The 1210s have held up well for me. They have good traction in mud and a moderate grip on wet rocks. As the name implies they were designed with the ultrarunner in mind.  I only wear mine for runs of under 15 miles and only when I want to stress my feet. I view them as a minimalist shoe but please remember that I love my Hokas.  I found the 1210s to be lighter and more compliant than the Cascadia 5s and 6s that I had, but a little more padded.  I have a pair of Asics Gel Scouts that I like better because they are softer.
