“SIZING SYSTEM is OFF”

“I climb at least three days a week...try to get in four days if I can. The Anasazi laceup shoe is a great shoe. I have a pair of the Anasazi Velcro. I bought what I thought was a US 5 1/2 Womens, the chart states comparable to size 4..I doubted this but when ahead and purchased this size. Whoa! Way off! If they had had my correct size , I would have exhanged them, especially for the price! This is a solid shoe but DO QUESTION their sizing chart.”
