Other than putting on some shoes to see if they fit right, how can you take them for a quick run around the block to see if you like them? Yes you can run on a treadmill and most running shops have them, but I find that treadmills are not the same as running on roads. Is there anyway to protect the sole of the shoe with some sort of protective covering so you don't scuff them on say a mile run in case you want to return them??
