Elegant Brooks running shoes in cream and tan. Lightweight and supportive. THIS WOMEN’S SHOE IS FOR: The Glycerin Stealthfit 21 is for runners who want a snug, close-to-foot fit and supreme softness in every step — so they can get lost in the comfortable ride and run distraction-free. This Brooks Glycerin Stealthfit 21 has been granted the APMA Seal of Acceptance. Predecessor: Brooks Glycerin Stealthfit 20. I used them for a couple of months and then my doctor told me my shoes were too small so it was too late to return. I only used these on walks but I have a running black pair too.
