Fit for Athletic or Everyday Shoes

Thorlos work optimally when fitted with your activity shoes. If you wear them with shoes that have already been fitted with your regular socks, you may feel your shoes are too tight. 

If your shoes are too tight, your feet may feel hot, cold, or just generally uncomfortable. 

Follow this guide to get the best protection and comfort from your Thorlos and your shoes.

  • Put on Activity Specific Thorlos when being fitted with the appropriate activity specific shoes.
    • Activity Specific Thorlos may increase your shoe size.
  • Select the activity specific shoe of your choice.
    • Choose the shoe size to fit the larger of your two feet (Most people have one foot larger than the other).
    • Purchase shoes by the way they feel, not by the size indicated
    • Try the shoes on with your Thorlos and feel how they fit
    • You should be able to move your big toe comfortably
    • There should be the width of your thumb nail between your longest toe and the end of the shoe.
    • The heel should fit comfortably with minimal slippage.
    • Notice that the ball of your foot fits comfortably into the widest part of the shoe.
    • Fitting should be done towards the end of the day, as the feet tend to enlarge slightly from the exertion of daily activities.

Fit for Boots

Note: Boots typically have a deeper last and thus there are fewer fitting issues with boots
  • Put on Activity Specific Thorlos when being fitted with the boots. Activity
    • Specific Thorlos may increase your boot size.
  • Select the boot of your choice.
    • Choose the size to fit the larger of your two feet (Most people have one foot larger than the other).
    • Purchase boots by the way they feel, not by the size indicated (Sizes differ among all shoe and boot styles).
  • Try the boots on with Activity Specific Thorlos and feel how they fit.
    • You should be able to move your big toe comfortably.
    • There should be the width of your thumb nail between your longest toe and the end of the boot.
    • The heel should fit comfortably with slippage of no more than ¼ inch; and the curve of the back of the boot should match the natural curve of the Achilles tendon area.
    • Notice that the ball of your foot fits comfortably into the widest part of the boot. Make sure that the boot flexes in the right place for your foot (at the last 'knuckle' on the big toe).
    • The arch area of the boot should 'wrap' snugly around the foot's arch area.
    • A key to proper fit is that the space between the eyelets of the boots when they are laced and tied should be about ½ to 1 inch - less than this and the boots are probably too large; more than this and the boots are probably too small.
    • Fitting should be done towards the end of the day, as the feet tend to enlarge slightly from the exertion of daily activities.
  • Purchase your boots and Activity Specific Thorlos as a system for maximum protection and comfort.
