Here's the update after a day of constant wear, for anyone who's interested. . .

They're 8-hour boots. And if they can be comfortable all day on my tortured feet, which sometimes rebel at my slippers, they should be really good for people without foot problems.

I found that they were a tad big in the heel, but I put in gel heel inserts, and that mitigates the slipping. My feet feel happy, too! Since they're suede, I'm going to give them a good squirt of waterproofing spray before it snows.

If you're looking for a more casual boot with an equestrian feel that will fit a narrow calf and is comfy to wear, this one may be for you. And they still have them at DSW!
