I wear a 12 D DO THEY RUN TRUE TO SIZE. AND WOULD I ORDER A M OR W WIDTH.
Sansha recommends that if you wear a men's size 11.5-12, that you order a size 18 in this shoe. If you normally wear wide shoes, then you will want to order a "W" width. If you typically do not wear wide shoes, you will want to order a medium, or "M", width. - DDS Customer Service (02/24/2014)
