First off - yes, they run AT LEAST a half-size small. Go up, especially if you have duck paddles (very wide) for feet as I do. You’re going to need the room.By comparison, I have been in the New Balance 1080 series for a million years, and their newest 10 4E (as of 2022) fits about the same as these Asics in the 11 4E. The NB shoes are great - and probably the most “4E” of 4E shoes - but over the years their premier 1080 line has, in my opinion, sacrificed substantive lateral foot and heel lineup support on the altar of waif-like lightness.I’m at the point as an active exercise walker where I need proper support just as much as I need cushion. Also - by the by, I have been using the Superfeet Copper replacement inserts found here on Amazon. They’re in the vein of “over-the-counter custom orthotics” and not the cheapest thing you’ll ever buy, but if you need them for support, you need them for support. Let the shoes themselves provide the cushioning. These Asics shoes out of the box are supportive and the cushioning is good. The Superfeet insoles slid right in as replacements for the factory set for that dash extra of reliable support and foot lineup.One more note ~ the Hoka Bondi 8s are comparable to the New Balance 1080s and these Asics 29s, but if you have wide feet, forget it. Their “extra wide” is a 2E *at best*. The shoe soles themselves are wide as moon boots, and probably give great support, but the uppers are strictly for narrow feet. Epic fail on Hoka’s end. Don’t believe me - read the reviews. They were slammed so much on their site that *cough* I don’t see reviews any more. Maybe I missed them on a recent visit?Fit-wise for my fellow ducks I’d say the 4E NB 1080s are best, flowed closely by these Asics 29s. Hokas … damn they were cushiony … are not for wide feet, period, unless maybe you get 2 sizes too big. Even then … ?But overall I’m going these Asics 29s for support AND cushioning AND width. ? As of this writing the 30s are indeed available, but at about $60 more per pair. The new-to-me 29s got great reviews, so I thought I’d start with them.
