I purchased these slightly used on a selling platform, but I cannot wear them. I am a new Brooks shoe lover but I did not do my research and cannot wear the Adrenaline line. Evidently they are best for over pronators and I need a neutral fit shoe (Glycerin works best for me, I have plantar fasciitis and back pain with standing). Love the colors. They are in amazing shape. Just not for me If you are new to Brooks, I also read you go up a 1/2 size and this is true for both pairs I have owned because I typically am a true size 10. Size is 10.5 B medium. There are sock fuzzies on the inside of the shoe, but not bad as you can see in the photos. Obviously previously owned as shown by the soles but tread great looks great and outside is clean. There is a bit of pink on the white as shown in the photos, may color rubbing. Barely noticeable. I am not a runner so never ran in them, only walked a time or two and then stopped wearing because of my personal discomfort.
