We’re now deep into autumn, and whether you’re into braving the dropping temperatures to get your miles in or are gearing up for your fall marathon, a little running shoe pick-me-up never hurt. This is where Swiss running label On comes in; the brand has marked down most of their last season pieces, which we believe you need to be shopping immediately, considering that the entire line of On’s best-selling Cloudmonster trainers are currently part of the mass of killer silos floating around at the last season section.

The Best Fitness Gifts for Everyday Athletes
Some people just want to get after it. Here’s what to give them.

We already knew that the Swiss athletic apparel brand wasn’t messing around when it came to elite gear and unparalleled performance — taking a sizable bite out of a running shoe market historically dominated by Nike and Adidas made that crystal clear — but as it turns out, they take discounts pretty seriously, too. “Last season” might be the official terminology On uses, but there are discounts on top-of-the-line styles we (your trusty InsideHook editors) still run in today, including the aforementioned Cloudmonster.

To that end, we’ve rounded up the full range of Cloudmonster styles from the last season section for you below, along with some guidelines to help you pick the trainer that’s best for you. Shop our picks from the On sale below.
