If you need a non-slip shoe for restaurant or housekeeping work and you have a narrow foot, your choices are very limited. Fortunately, Skechers makes a non-slip lace shoe for men that — even though sized medium — runs narrow. The style is called Rockland-Systemic and can be purchased from Zappos.com.
First and foremost, this shoe is great because it laces (as opposed to being a slip-on style), which is always better for the narrow foot. Also terrific is the fact that there are 6 sets of eyelets: the more eyelets there are, the better the shoe fit, especially for a narrow foot.
Finally, there is no hourglass in the waist of the shoe, which provides support in the arch where needed most. This also makes for a stable foundation if orthotics are to be worn inside the shoe.
