Brands release new variations of the same running shoe over the years, building on the successes and failures of each one that comes before it. Since the release of the Brooks Glycerin 21, we've seen a price drop in the Brooks Glycerin 20, plus its GTS counterpart.

Don't sleep on savings directly from Brooks, either. From November 21st to December 4th, take 25 percent off of full-price apparel—and on December 3rd, you can get an additional 10 percent off with the code CYBR24. (You read that right, no "E"—it's a play on letters for BRooks, get it?)

Dick’s Sporting Goods has a few good deals on Brooks sneakers as well. The Catamount trail running shoe is also on sale at the moment and marked down as low as $127.99. With deep treads and multiple sizes to choose from (this sneaker also comes in medium width) the Catamount has a lot to offer.
