Query: bloodied foot

Went on a day trip with my new Sebago mens spinnaker boat shoes. By the end of the day my right foot was very red and almost bleeding. On looking at the shoe the stiching inside the right shoe was bunched up and causing the shoe nto rub against my foot. Further investigation showed that the right shoe actually was a different shade than the other. Come to find out it was the last pair available. I believe the shoes were returned and than sold to me. How could anyone with a conscience offer a product like that.
