I just started a new job and I am on my feet, walking around 5-6 hours at a stretch at an upscale venue that requires nice shoes (ie: heels, cute flats). I haven't done this in a while and my feet are killing me! I have high arches and am desperate for any advice about protecting my feet so I'm not in pain by the end of each day. And, tennis shoes/crocs are not an option. (Oh, and I know they're atrocious but support hose? No?) Thank you!!!
