How about a pair of supportive but soft footwear to wear after workouts. For example, I have these for my gym shower shoes: www.konasports.com/crocs-recovery-slide-me
...I'm not sure they are made anymore, but I was able to find some for sale: www.6pm.com/crocs-prepair-flip-black-silve
However you may just have to investigate if they make any similar products. Honestly, these didn't feel that much different from some of the other crocs models but they came with glowing endorsements from some other fitness people and they were very inexpensive when I got them.
Another good choice might be Birkenstocks, especially the ones with the newer soft footbeds. I'm not sure what they have between the cork and the footbed lining but they sure are soft compared to the old ones. Comparatively little break-in time WRT the older style.
