I received this product on March 30, 2019. Unfortunately, I didn't wear them until mid to late April. I have several pairs of these Propet shoes and have always been satisfied. However, this time the left shoe has a flaw on the outside, about 2-3 inches from the left pinky toe. There is something similar to a pebble or a nail in the fabric. I thought I would get used to it over time. After weeks of foot pain, I realized the shoes were defective and would never be comfortable enough to wear. I know it's already past the return date but I think with my past at Propet and Revain I might be able to get a replacement. Please let me know. Thank you James Redmond.
