This is a very comfortable shoe with appropriate room for the width of my foot and toes, feet feel comfortable and secure. I ordered a 10 whereas I wear a 9 in everything else. Back 10 years ago, I was a solid 8.5 American size. I am a European size 40, and a British dance ballroom dance shoe size 6.5. I ordered a size 10 based on reviewers comments and it is perfect. Thank you reviewers. This is a very nice dance workout shoe.
