I bought these Superfeet GREEN insoles at the suggestion of my orthopedist a while back (I am very active and have arthritis in my feet - boo!). I opened the box (which definitely looks like it's been in my closet for a while) and pulled the insoles out to look at them, then decided to wait on using them. And then...never used them. I'm cleaning out my closet right now and I think it's best to move these on to someone who can actually get good use out of them! Size: Mens 7.5-9; Womens 8.5-10 Box description: "Fit profile: High-profile insole with the shape that offers the widest and deepest heel cup for maximum support." These are supposed to be amazing...I know lots of hikers / backpackers who use them...I just have such finicky feet that I can't bring myself to throw out my comfy insoles to swap out.
