Query: What was I thinking?

I didn't pay close attention when I ordered this... silly me for thinking that just because the shoes come in pairs, that the stretcher would too. Why would I only want to stretch one shoe at a time? Why would I want to pay twice this for that priviledge? I have to learn to pay closer attention for what they are NOT telling you, before I put an item in the cart from now on.
