Excellent Shoe, Firm Cushioning

Overall
I’ll definitely buy these again. Solid trainers. No issues running 40 miles/week for 10 weeks. Good traction on most surfaces. Cushioning is good and firm. Some trainers make it feel like you’re running on a sponge. Not these ones.

I’ve always struggled to find a good running shoe that fits my feet in width for the toe box and heel and still provide comfort, cushioning, and durability. The Brooks Glycerin 21 Mets all those needs.
