I started buying inserts for my shoes to reduce the pain from standing at work. I never bothered to throw out the old ones, just place the new one on top. With all the inserts I get an extra inch. I wear chukka boots. They can be dressed up, and are roomier. Being roomier you can pile the inserts in and still have enough space for your foot to be comfortable. Doesn't feel like I'm in heels. It's just squishy.
