Hello. I've purchased your products over the years and found the quality quite good. I recently purchased a Fairbanks Slip Omni-Heat., Men's Size 11 Grey179124*-***. When I tried to put them on for the first time, I could have sworn I'd made a mistake and bought the woman's model (if there is one). I couldn't easily get my foot through the top opening! My feet are not abnormally wide for a man. I suppose that if I work the top long enough it may stretch out in time, but why should that be necessary? I would suggest that future slip-on type footwear have elastic material sewn in at the top to make use of the product less difficult and to keep the top opening firmly in contact with the foot when in use.
