For myself I love Ryka sportwalker, walking shoe. You can find them at Lady Footlocker, or footlocker.com. I have been wearing them for years, just keep buying the same shoe as I wear them out. They are made for women's feet so they fit wonderfully.
For a great sandal..I love my teva's. Like walking in tennis shoes, very comfy.
My hubby..likes the new balance 609 cross trainer for walking around the parks. Now, it may have a different number for 2005, he hasn't got a new pair yet this year. You can easily find the new balance mens cross trainers in Pennys, foot locker, sports authority. If you find them at the right time they are $39.99. One of the best bargains ever for shoes.
As far as sandals for him..teva's all the way.
Good luck shoe shopping!
