Free Range Pro

The Pro takes So Ill’s Free Range and adds a stiffer forefoot (for edging), a retooled heelcup, and a split sole for better front-to-back flexion. As with all the So Ill shoes we’ve tested, the Free Range Pro has soft, gummy rubber (in this case, Dark Matter) that helps it excel at some things—namely gym climbing, and grabbing and scumming—but perform less well at others—namely edging, which our tester felt was “rolly,” though he was testing in summer’s heat. However, given that these are advertised as a “maximum performance workhorse” designed in concert with the V15 boulderer Toshi Takeuchi, they certainly excelled at their stated métier—steeps—doing “marvelous at keeping my feet on, on steep, bouldery roof problems,” thanks to their extremely downturned, pointy toe. The main ding was the heel: Even with his toe jammed hard into the toebox, our tester nearly lost the shoe in a few athletic hooks, and would have preferred that suction—and not just the Velcro strap—was holding the shoe on. He did, however, note a low-volume fit, while he himself has wider dogs—it may be a foot-shape thing.
