The first pair I received was defective so I had to send those back. Looked like they had been returned for the same problem before. It had two plastic strips glued inside and would have rubbed blisters and was uncomfortable. The replacement was easy although I did have to buy an envelope to return them in. The second pair arrived promptly. No defects. Fits like a glove. Buttery soft and very comfortable. I would have given 5 stars if I hadnt had to return the first pair for defects and  for the simple fact that I had to buy an envelope to return them in.
