I really wanted to like these because I love the mary jane with the same sole (Hazel), but the upper edge along the inside arch of the foot is stiff and rubbed my foot in a way I knew I'd get an instant blister.  The back of the heel also felt like it might cause a blister.  I considered keeping them and just taping my feet for every wear, but decided to search for a shoe I can wear without risk of blisters.
