This year so far I've gone very slip-on crazy! I started with the perforated white Vans (took a little breaking in, some band-aids and foot glide, but now good). Then I added the Ash Jordys (now on sale!). I really wanted the Ash Kurts to work, I tried them in two sizes, but they are too narrow for my wide feet. What I've replaced them with is the Steve Madden Buhbba. Almost 1/3 of the price of the Kurts, not quite as cool looking (the Kurts are so modern!), but they fit my wider feet. Haven't worn them out, not sure how well they will wear. My plan is to only wear them with specific outfits, I don't see them as every day shoes like the Vans or Ash sneakers.
As far as sandals go, I purchased several last Summer. Some are all still available on Amazon. They all work well on my high-volume feet. The SE Ardellas look great with skirts. The Matiko is a good neutral sandal. And the Donald J Pliner Corso is my favorite slide. It's not great for long walks as it's a clunky slide, but I love it for short errands. It looks great with so many things that I ended up buying a pair in black as well as gray. It is well made and right now, priced so low -- I would recommend this to any of my high-volume foot sisters with a lazy streak. (A slide is the ultimate lazy shoe don't you think?)
Finally, I added the Find for the Brooks Chariot sneaker. Again, great for high volume feet. I didn't keep the ones in black but plan to purchase this shoe in a different color when I find something that strikes my fancy.
ETA -- the Matiko Ursina isn't available this year, but they brought back the Bryn from 2 years ago. I added.
