For "real" athletic sneakers, I wear Altras -- one pair for trail running and hiking, one pair for road running. They've more or less solved most of my foot/ankle/knee problems, so I won't be switching my allegiance anytime soon.
For casual wear, I've not been very into sneakers lately, maybe because they're so *everywhere* right now. I used to be a HUGE Converse fan, and I still have a pair of Chucks, but don't wear them often. Partly a comfort thing, partly due to the fact that they are printed rather than solid color, which reduces their versatility somewhat. But I knew that when I bought them, and I still do love them.
I also have a pair of Allbirds Loungers, which are sort of my go-to around-town shoe right now. I suspect they make my feet look huge, but whatever, they're comfortable without socks, which makes them good for days like today, when it's chilly in the morning and I'm too much of a wuss to wear sandals or even little canvas shoes.
Speaking of little canvas shoes, these are the sneakers that have more or less replaced my Converse: http://xeroshoes.com/shop/ipari/lena/
They run very wide, which means I can comfortably put a thick, wooly sock inside them. I wore them all through our dismal, cold spring as an alternative to boots. At first I thought the loose fit would drive me crazy, but having a "transitional" sneaker that can accommodate a boot sock proved out to be a sanity-saver, because by March/April, I am just so sick of boots...
Okay, so for a person not very into sneakers, I kind of have a lot of sneakers...
BTW, those Ahnu hikers are *great* shoes -- I had a pair of the Montara hiking boots, built on the same last, when I was pregnant; they were the only shoe I could wear for more than a couple hours. I adored them. I recommend Ahnu to everyone looking for lightweight trail/travel shoes that look decent for casual wear. I added a cute pair of insulated Ahnu boots last year that I've been very happy with. I think they're actually made by Teva, or owned by the same parent company or whatever...
