Asics’ 3D-printed sandal offers post-workout comfort
 

The theory and practice of marginal gains is to find and fix hundreds of small things that, in aggregate, add up to something vast. Asics believes that there are gains to be made in what runners wear when they’re at home as much as what they’re wearing on the track. That’s the pitch for the Actibreeze 3D, a pair of 3D-printed sandals with a lattice structure designed to improve cooling and breathability. The idea is to stop your extremities from getting too sweaty and tense after a run, so you’re that much more prepared for your next one. I’ve been wearing a pair for a couple of days now, and while they do keep your feet cool and dry, they’re not perfect.
