Black Friday is the unofficial kick-off to the annual holiday shopping season but, for runners, I’d argue Memorial Day has more to offer. Hear me out. If you’re anything like me, you’re not really thinking about your running shoes then nearly as much as you are now—the weather is getting warmer and mileage is growing as you train for a fall marathon. We’re also getting close to the time when many brands refresh their lines, hustling to get new shoes on feet ahead of those fall marathons. That sets up for good sales on shoes when you need them most. We’ve rounded up nearly a dozen pairs with steep markdowns. But hurry before your size disappears.
