Product Summary
The TYR RNR-1 Runners have a lot of promise for a running shoe. While they are slightly heavier than some other options, they've proven to be very durable in our testing, and we love the ultra-responsive midsole thanks to TYR's Surge NRG+ Foam and Pebax support. The outsole has also proven grippy in slick conditions, and there's plenty of wiggle room in the midfoot and forefoot for wider feet.
