I’ve been wearing this model for 30 years. They were recommended by a naturopath as a possible solution to my back problems. I’ve tried several different orthotics before I bought some Burks.I was in Cannon Beach, OR. I had been walking around; but I was in quite a bit of pain. I noticed a shop advertising Birkenstock shoes. I got a pair of Arizonas. Within an hour…I was almost pain free. Over the years I have tried several of their other models. They used to make a a work boot that I loved back when my job required that I stand all day. They don’t make that model anymore; but I recently bought a different work boot that is very comfortable and great for long walks. I’ve also got a pair of dress shoes that have lasted for 20 years. I only wear them 2 or 3 days a week, and I don’t walk very much in them; but that’s still a remarkable amount of service for the money. My Arizonas usually last a 2 to 3 years. But I pretty much live in them. And yes…I wear socks with them. Let the “fashion police” be $
