Rating: 4 out of 5 stars – 53 ratings
Includes a few 5 star reviews from narrow buyers who said the boots were very attractive, made of very soft material, comfortable, supportive, easy to put on and take off, well-made, and a great fit for narrow feet. One of these reviewers bought the super slim width to avoid any heel slippage, and planned to use a stretcher to ease the width of the toe box.
Includes a 4 star review from a narrow buyer who recommended sizing up a 1/2 or full size.
Also includes a review from a narrow buyer who said the narrow width was too narrow in the toe area but not narrow enough in the heel, and reviews from narrow and super slim buyers who both said their respective width shoes were too narrow.
