Brooks Glycerin 21

Brooks Glycerin 21, crafted with nitrogen-infused DNA Loft V3 midsole, offer lightweight and responsive comfort. Ideal for walking and running, the lace-up closure of these sport shoes offers a secure and comfortable fit. Neutral support designed to deliver comfort and durability for a neutral stride that doesn’t need additional support. Easily accommodates custom orthotics when original manufacturer foam footbed insert is removed. Breathable engineered knit upper. Heel to toe drop 10mm. Shoe weighs 9 oz. I ended up needing a half size larger. I’ve only had these shoes since July 16. I’ve found the 1/2 size up to be more comfortable for my feet and can’t return the sz 9 where I bought it from.
