Twenty questions: forgotten Christmas gift edition!

Earlier in December, David bought me this for Christmas:

Runner powered by coffee

I know he bought it, because we were placing an order for several items at the same time, and he's not very discreet. But then he forgot all about it.
I didn't, and I'm making him play "20 questions" until he guesses what he bought me and forgot about.
Question #1: Is it running related? Yes!
