I have always loved Easy Spirit shoes, for any job that requires significant standing/walking. They have (fairly) recently started a male line. The shoes are generally wider than average, and very comfortable, but I think you have to have the right foot shape. I’d suggest you try on the shoes.
I’ve been wearing the same pair of Ecco shoes for a couple of years now and they still look great! I highly recommend them for incredible comfort and durability. I’m also a tech and wouldn’t consider buying anything else.
I have no problem with shoe comfort. What kills me is heat. I’d be barefoot or wear sandals or sockless Bass all the time forever if I could. What shoes are not HOT?
There are plenty of sneakers that are made with mesh or other materials that breathe well.
For shoes, many Birkenstocks are roomy enough that there’s surprisingly good ventilation, since there’s room for air to circulate round your feet as you walk.
