I am pretty fussy and demanding of the gear I use. I figure if I am paying good money I expect it to perform to an expected standard. I also go to places I really don't want my gear to fail. So my assessment of gear will always be harsh and fully frank. But that's what you want. I won't endorse a product unless I use it myself.
I have been lucky to receive support in the form of product for one of my most essential pieces of
equipment: my socks. Injinji toesocks are without peer in protecting my feet in ultras and I would never consider running in anything else.
