I recently had surgery on my heel to remove a benign tumor. I have wide toes that are C width. I also have plantar fasciitis. I'm looking for comfortable flat shoes that are completely backless. I also have cold feet. I work in an office without a dress code. I've ordered Birkenstock Arizona and clogs, as well as Bella-Vita mae slides, Soft Walk Tillman, and Calvin Klein Irene slip on sneakers. I ordered from Amazon and Nordstrom for ease of returns. If you have any suggestions of any other shoes that would be good for me, I'd appreciate them. I have fussy feet and I never know what will work. Thanks!
