Includes a few 5 star reviews from narrow buyers who said the shoe is very comfortable, with adequate room at the toe and good arch support.
One of these reviewers has worn the 860 model shoe for years. The reviewer purchased medium width shoes when narrow width was not available, and was surprised that the medium width fit well and was very comfortable.
