Is it hypocritical of me as a vegan to...?

Before I became a vegan I bought toms(shoes), which have a suede sole. Now that I'm vegan, I still wear them because I spent a lot if money on them. On one hand, I understand why it would be wrong; I mean, vegans don't wear animal skins. But on the other hand, I already bought the shoe, the animal is already dead. So why throw them out ?
