Thanks for the laugh, OP! I couldn't understand the title of your post for the life of me, so I clicked to find out what the heck "grandma ankle" is. Now I get it. Cracking up on the sofa.

Go without!

if I couldn't find a rubber band I'd go without I think.

Thanks, PPs!

I'm on the metro on the way to a court hearing, so no time for CVS and no hiding feet under desk! I'll try the rubber band thing if I can find one.

Other votes/ideas?

find a rubber band to hold it up--make your own garter. of course be careful you don't cut off circulation.

or better yet, pop into CVS and buy a new pair. keep a spare at work too.

Sweaty feet! Kick your shoes off under your desk.

Walking to metro on way to court and the elastic on one of my knee-his gave out. Do I take them off and have massively sweaty feet all day, or leave them on and deal with yanking/grandma ankle all day.

You decide!
