APMA Seal of Acceptance
APMA Seal of Acceptance

The American Podiatry Medical Association (APMA) Seal of Acceptance recognizes products that promote good foot health. At Brooks, products across seven of our key franchises feature the APMA Seal of Acceptance. This Achievement highlights our leadership in biomechanical research for runners and anyone who spends extended time on their feet.
Now the Glycerin 21. It is a good looking sneaker even in a wide width. It is a quality sneaker, really well made. I have bunions and arthritis in my feet. I am a very active person and supportive sneakers are essential. I did need to add another small layer of cushion. I added a dr. Scholls thin shoe insert and it was perfect. I am able to use orthotic inserts in these sneakers if necessary. I remove the lining to do so. But, I have found the support is so good that I do not need them. I have recently purchased two pair. I have the black for an understated look and the black snd white for a sporty look. Both have been great. I am a fan!! Can’t beat the brooks return policy. I had ordered some different sizes, and returned the ones that didn’t fit. I’d love more colors in a wide width! Maybe something in a cream or blush??? The Glycerin 21 has been a lifesaver for me. Gave them a 4 only because I had to add the insert to get perfection. Maybe really a 4.5!!
They look… puffy. Not sleek like the older versions. The 21 seems to have slightly less room in the toe box to me, but they are still comfortable.
Overall I enjoy them.
