Sizing standards vary among different manufacturers, so we recommend that you order the size that normally fits you best. Shoes For Crews footwear tries to maintain consistent sizing for all of our different styles, and our sizes generally run true to the European sizing standards. All available sizes are displayed in the Select Size drop-down menu on our website. If a size is not shown in the list for the style that you are viewing, then we do not make that size. If you are between sizes, we recommend that you order the 1/2 size larger.  If your shoes do not fit, don't worry - you are covered by our Satisfaction Guarantee, whereby you can return your unworn shoes for another pair FREE of charge.
  1. The best time to measure and fit shoes are when your feet are at their largest, usually in the late afternoon or evening
  2. Always try to fit your new shoes with the same tights/socks you will wear regularly with this type of shoe
  3. If you use your own insoles or orthotics inside your shoes, consider the extra volume when fitting new shoes. If your new shoes have a removable insole, remember to remove this and replace with it with your own insole or orthotic. Insoles or orthotics affect the way a shoe fits.
  4. Select a SFC shoe style that best matches your foot shape.
  5. Make sure the widest part of your foot (the girth around the ball) fits comfortably into the widest part of the shoe. Shoes should be as wide as your feet and a thumb’s length (1/2 inch) longer than your longest toe when standing.
  6. Wiggle your toes to make sure you have enough toe room.
  7. Don’t select a shoe too small to avoid heel slippage. Your shoe should fit comfortably across the top part of your foot, even when new.
  8. Boots are more supportive and durable but may be heavier and less flexible in the top part of the shoe.
  9. Try your new SFC shoes at home or on a clean surface for a few minutes before deciding fit and comfort.
  10. Remember the size of your feet change as you grow older, normally they get larger.
  11. Don’t buy shoes too tight and expect them to stretch to fit. They won't.
  12. Thick soled shoes cushion your feet better on hard surfaces.
  13. A laced or Velcro® closure shoe usually fits more securely than a slip-on or pump style.
  14. Low heeled shoes are more comfortable and safer than high heeled shoes.
