I was very confused about which size to order because other reviews said to size up or size down. I decided to go with my usual size 7.5 and I'm really glad I did.  They fit perfectly, not wonky. They are not too narrow for my wide feet.  Too room was perfect and my heel didn't hang off the back.  In case in matters is all with my bare feet.  If you always order a certain size (not a range of sizes), then order your regular size.
