Hoka "takes a cue from nature" and updates the Hopara 2 hiking sandal with merino wool for better breathability, less stink

Hoka Hopara 2 Aerino.

Just a year after Hoka launched the funky Hopara 2, part hiking sandal, part hiking shoe, the brand has unveiled an updated version that takes its cues from nature to make it more breathable than ever.

Rising temperatures are on the way, so it's perhaps no surprise that the California-based brand is thinking about how to help hikers deal with sweaty feet. The answer? Merino wool.
