New Balance Velcro Walkers have been good for me for the past 5 years.
The style that sells for about $60-$65, I haven't tried the more expensive $80 or so, as the others work well.
Also the Dr. Scholl's Velcro Walkers fit well too. I switch between the two.
I also remove the innersoles & arch (I have flat feet) and use full gel innersoles topped with a foam cushion innersole because my feet are sensitive and need cushioning.
