My Right Foot

Does anyone know where I can buy a single right shoe? A gym shoe, to be exact.

I knew that as I lost weight, my feet would get smaller. But I expected them to shrink at a similar if not equal rate. How silly of me. As it turns out, my right foot has sped past my left foot in the getting-smaller department.

On my last gym visit, I noticed that my right heel was coming out of its shoe as I walked. I tightened the shoe. My heel again came dangerously close to escaping its confines. I tightened the shoe once more. Same story. My left foot, by contrast, still fit snugly in its shoe.

So, I ask again, does anyone know where I can buy one right gym shoe?
