I don't see Earth Brand shoes wvery much in Canada. I sometimes see them at Winners but I think that the Shoe Warehouse stores have some Earth brand shoes. I was also at a Walk with Ronsons shoe store at Metrotown mall in Burnaby B.C. and that store had so e cute Earth shooties but at nearly $80 CDN on clearance, I don't know.
Edited to add that I went to another Walk with Ronsons shoe store today that had some Earth brand shoes in the shootie style and they were not very comfortable. The footbed had sewn in padding under the heel but I could feel the thread edges that stiched those pads into place. Also the ankle area leather was too stiff and thick and not very soft when walking around the store, it dug into my ankle bones so I would not have bought those shoes even though they fit in the forefoot and the sizing was OK. I felt that the leather quality wasn't up to my standards.
I do have a couple of pairs of Earth ballet flats with cross straps that are comfortable. I have had those shoes for more than a year and I would buy them again. I know at the time I bought them at Winners that QVC sold them too but I think they have been discontinued. They have a removable footbed that is somewhat orthotic but the footbed is not hard as a rock like Vionic.
