Toe seat for 12D was too tight. I wore them for a very short run and a short walk (less than 5 miles total) and ended up with a huge blister on my toe. I always wear 11.5 or 12D (never had to buy wide shoes before) so I was surprised. However, the cushioning in the sole of the shoe was very comfortable. I really wanted to like these shoes but they were too uncomfortable due to the tightness at the toes. I had to send the shoes back.
