I had to return shoes once after wearing (to Nordstrom) because the sole was defective. I'd never return something I wore just because I decided I didn't like it. The store shouldn't take a loss because I chose to buy something I ended up not liking. I'm all for defective items being returned, but returning after wearing for no reason is abusing the store, IMO. You should have determined you didn't like them before wearing and within a reasonable period after purchase.
