If you're walking recreationally (maybe less than 10km in one go) shoes are mostly irrelevant. No, you shouldn't use Wellington boots, I guess.
Nike makes some good walking shoes that skew wider, but definitely read the reviews first to confirm, since they change between model years/revisions. For a while Downshifter was my go to, recently the Revolution 6 has been a good replacement.
However I got pediatric inserts designed by a foot doctor. What he didn't tell me was that for those kinds of inserts it is better to wear a wide shoe which accommodates the inserts, but "neutral". I still was wearing my supinator shoes. So it will not "overcompensate". This advice was from a specialist running shoe shop. When I tried the neutral one he offered me on one feet, and the old "overcompensating" shoe I had, I noticed the lack of stability immediately.
I have a friend whose problem is that their feet sweat more than usual. In their case the solution was shoes with extra ventilation around the soles.
Also: soles wear out! If you walk/run more, you need to replace your shoes more often.
Nothing fancy, just whatever is cheap and catches my eye - I usually go through 2 pairs a year.
My current pair is far overdue! Anyone here have experience with the Gore-Tex 880's, are they good?
I'm quite overweight, and my tennis shoes last me ~6 months in good shape.
* Used for running when new, usually for a year.
* In their 2nd year, for walking, gym and casual use.
* In their 3rd year, for gardening, house maintenance and stuff like walks in muddy places.
