Dr. Grip. I love the “shake to advance” thing and the huge, squishy grip.

Not quite. I was shopping for running shoes a while back and learned that generally, a women’s wide is the same width as a men’s standard. I think a women’s standard is usually called a B width, and the women’s wide and men’s standard would be a D width. Some brands do make other slight differences between the men’s shoe and the women’s shoe, so the swap might not always be 1 to 1, and some brands do unisex sizing, so there’s no difference in width for men’s vs. women’s.
