While maybe not as ugly as bowling shoes, weightlifting shoes are pretty unattractive. But, if you are considering getting into powerlifting or Olympic style lifting, they definitely serve a purpose.

The shoes are designed to fit snugly. If you are lifting heavy weights, you don't want your feet sliding around. And the heels are raised and non-compressable. This gives you a firm & solid base and helps you get under the bar.

If you are going to be consistently lifting heavy, weightlifting shoes will come in handy.
