Most women's running shoes of my size are much cheaper than the men's. I'm not picky regarding the color as long as it's not pink or mauve. But what bugging me is some shoe makers (nike, mizuno, asics ) start to sell "gender specific" shoes. I wonder if this trend is only a gimmick or it makes a real difference. I agree that men and women don't have same physiology. But I'm not sure the differences are significant enough to justify two types of shoes.
