Collins is super comfortable and such a beautiful sandal. I love that it patent because the touch of patent on the sandal makes it unique and classy. I love that they can be dressed up or down. I purchased every single color. Please make more colors and I will purchase every one! They do run small. I am a true size 9 across the board in Tory Burch etc. I have long toes and medium width feet. In the Collins I wear a 9.5. Thanks to the awesome Lorena in customer service who helped me figure out just what size I needed . In the Jack flat I wear an 8.5 which she also figured out. I was able to get my order right the first time because of her professionalism and help. I was reluctant but she was spot on!
