Don't let wintry conditions hold you back from your running goals with the GEL-NIMBUS® 21 Winterized men's running shoe by ASICS. Built to last, it's carefully designed with advanced technical features giving you luxurious cushioning, helping propel you further than you thought possible. I.G.S® (Impact Guidance System) technology allows your foot to perform in a more natural manner, freeing you up to focus on the important things: your breathing and pace. GEL® technology in the fore and rear foot absorbs the impact of your landings, thanks to shock-absorbent silicone which offers comfort over the distance. It's crucial to have a spring in your step on those tough winter runs, so FLYTEFOAM® Propel lightweight foam has a high-energy return elastomer for excellent bounce and toe-off. The GEL-NIMBUS® 21 Winterized shoe is fitted with a SpEVA 45 lasting, a plush midsole material for extra comfort, while the TRUSSTIC SYSTEM® technology helps keep you in your natural line of motion. We've fitted the shoe with an external heel counter, holding on to your heel firmly for an adaptive fit. To last the miles, an AHAR® outsole made with High Abrasion Resistance Rubber works against heavy contact areas of the sole, to reduce wear and tear. Made with a mesh upper to help air flow around your foot, let your shoe take the strain while you push yourself to achieve more.

Great designBought a pair of these in November when it was offered for a deal I just can't pass up. Design is awesome, but they don't feel true to size to me. I wish I could've gotten it .5 size bigger but asics don't offer exchanges and I didn't want to return then buy another pair anymore. And besides, the size I would like is no longer available. Anyway, been wearing thinner socks and they seem to be stretching now that they're being broken in. I had to take out the inserts it came with, they feel stiff and not cushiony enough. I'm using an aftermarket memory foam inserts now and everything's good so far.
