How do I decide if my feet are Narrows or Regulars?
Width classification is part art and part science. In general, if you always wear narrow shoes, don't have a wide toe box, and consistently hear remarks about your slender feet, then Narrows and Mediums are right for you.
Most feet are best suited for Regular and Medium width footwear.
