Hi Ray, I have several pairs of Xero shoes and you can use orthotics in them. They have a few of the slip-on types in the below $80 range but most are in the $120 to $180 range - https://xeroshoes.com/. Last month I bought a pair of Birchbury Bramfords that I like a little better mainly because they have elastic laces and I can slip them on but they were $120. Basically they are a leather tennis shoe which I think is a better quality than the similar canvas slip-on from Xero - https://birchbury.com/pages/bramford

For me, the most comfortable are my (soft sole-their specific feature on some of their shoes) Birkenstocks. I like the open toed sandal style and although I look like a total nerd, I do wear socks with my sandals when my feet become icy. The shoes aren't cheap 125+ but totally worth it for their comfort. I find that I do not need to wear my orthotic with these shoes. They provide great arch support. min

Ray, a shoe store known for orthopedics fitted me with shoes from Brooks with a big "toe box."
Specifically their model "Addiction GTS 15" size medium (D). It accommodates my orthopedic foot brace. If you phone the Brooks company, they can tell you which styles have a large toe box. The shoe cost a lot ($180??), but I have worn it 3+ years.
