I’m not much help on the specific question, but I hate to have it die on the vine. So, I’ll offer what advice I have.
I know a couple of people who shop at DXL and I’ve heard them recommend it to others, so I’d check with what they’re offering. The guys that I know that shop there dress well.
The other place I’d look is Bonobos. They’ve got a wider selection of sizes than most retailers and I’ve been happy with everything I’ve bought from them.
Clark chukkas are one of my go to nice, and casual shoes (boots). The Clark’s are great value for the money too. I like their Wallabees too, but those tend to be pricier and are a less universal style.
A clean pair of Adidas Stan Smiths can look good too. Really any of the simple sneakers will look good with most outfits, like these, the Nike Cortez, or whatever. I don’t like sneakers that look too technical or chunky, but that’s just me.
Johnston and Murphy has a mixed reputation and are expensive, but I’ve liked the two pairs I’ve had from them. They’ve been worth their price too, the last pair I had from them lasted about 8 years.
