I switch between my super comfy tennis shoes and my croc slides (cleo style, not the bulky traditional crocs). I know you aren't a fan of crocs OP, sorry, I swear by them, and don't have other sandal suggestions....however, I can highly recommend no matter how comfy your tennis shoes are, buy the Dr. Scholls Gel inserts. I just buy the 1/2 ones, either arch support or heel support, as there are a few choices. Makes a big difference for achy feet.
For blisters, I read on one dis forum a few years back about spraying your feet with spray deoderant, and I swear it works! It keeps your feet from getting so sweaty and seems to help with blisters as well, although I'm not super prone to blisters to begin with. Also, as others have said, true athletic socks make a big difference, the rule is NO cotton. I don't wear wool, but just some lightweight athletic socks, and just make sure they aren't cotton.
