Podiatrist ruined my shoes

Went to podiatrist today for the first time due to calluses on my bad foot (Lisfranc surgery in 2019). I was wearing expensive Olukai shoes that are one of the few nice looking tennis shoes I can wear to work. He said he would sand them down where the callus is and that I would have immediate relief… well it feels terrible to walk in them now. I feel like he ruined my expensive shoes and now I am frustrated. He said to bring in other shoes I wear a lot for him to “fix”. Now I don’t know what to do.
