Some folks were interested in finding what runners at the Superior Fall Races (100mi., 50 mi. and a marathon) were wearing. I have no information on the Superior Races, but Drew Robinson, Trail to Peak, has reported on survey results for finishers in the Western States 100 Ultra-marathon in California’s Sierra Nevada… in 2014, 2015 and 2016. He looks at market share of running shoes, socks, packs, and headlamps. This is good information!
