I am an over-pronater and have had problems in the past with fasciitis and tendonitis. I got these to use as a work shoe in a hospital. The shoe is well made and very stiff, but when I put them on I felt like the pronation was even worse than in my bare feet. My feet we're hurting within minutes. I ended up buying Birkenstock Boston Clogs instead and have been very happy. Will be donating these to Goodwill.
