It depends on how far your walks are. I usually walk 8-12 miles a day on average. If it’s a nice weekend, the pup (husky) and I can get 15-20 miles in. The Des Moines trail system is like a dream come true for us.
Going for a mile or less? On Cloud 5’s would be fine. They are stylish and pretty comfortable. Not sure I would take them anything longer than a mile though. It’s also very easy to get rocks stuck in the outsole.
I’m a big fan of the Brooks Ghost line. The Ghost 15 have been awesome. By far my favorite shoe to walk in.
My gf (no pic) is a nurse who’s on her feet most of the day and swears by her Hoka’s. She wore Brooks before that but prefers Hoka’s. Standing/short distance walking is very different than long distance walking though.
I would not look to Nike, Under Armour, or Adidas. Look for the brands whose sole focus is running/walking. ASICS, Brooks, Hoka, Salomon, Saucony, etc.
