Your Thorlos activity-specific clinically-tested padded socks (CTPS), your shoes and any inserts or orthotics prescribed or recommended by your doctor or foot health professional will work together as a system of foot protection and comfort and should be tried on and purchased together. This will allow you to achieve the optimal shoe fit with your Thorlos CTPS.
Here are two ways to ensure you get the best possible fit when buying new shoes so that your feet can move properly inside your shoes. This will maximize your foot health, enjoyment and comfort during and after participating in your favorite activities.
Here’s what we recommend in a self-service store:
- Choose the appropriate Thorlos padded socks in the proper size
- Wearing Thorlos, try on activity-specific shoes in the size you normally wear
- Walk around the store
- If your feet feel a little warm or snug, try increasing your shoe size by half a size until your feet feel just right—you will know you have the perfect fit when your feet say, “AHHHhhhh”

Institute for Preventive Foot Health’s Professional Fitting Protocol
This is how to proceed when you are working with a foot health professional to ensure your Thorlos, your shoes and any inserts or orthotics work together as a system and that you achieve the optimal shoe fit with your Thorlos. This approach is especially important for people with feet at risk, such as those with diabetes, other circulatory problems, arthritis or serious foot conditions. Or watch IPFH’s Professional Fitting Protocol videos.
- Your professional should start with a foot assessment, gait analysis and sizing determination. Ideally, he or she should measure your feet with a Brannock device or another equivalent measurement tool and do so each time you buy new footwear, since your foot shape, size and any foot conditions you may have can change over time, and because different styles and brands are sized differently.
- Your professional should select a clinically-tested padded sock made for the activity in which you will be engaging – for example, walking, running, hiking or casual wear. Wear (or take with you) the clinically-tested padded socks you will be wearing when you are measured and fitted for new shoes.
- Your professional should select shoes/boots that are appropriate for the activity in which you will be engaging. They should be roomy without letting your feet slide around. The professional should feel inside the shoes to make sure there are no rough seams or raised areas that can create pressure points or rub the skin. The toe area should be rounded, broad, deep and shaped like your feet (no pointy toes). If the shoes have laces, the tongue should be cushioned. For most of us, one foot is larger than the other, so choose shoes/boots that fit the larger and wider foot first.
- Try on your activity-specific shoe/boots while wearing your clinically-tested, activity-specific padded socks. If you are using inserts or orthotics, place them inside the shoes first. If you use a full length insert or custom orthotic, your professional may remove the foot beds that come with the shoes before placing the inserts or orthotics into the shoes.
- Your professional should check the heel and ball width and toe room by pressing a thumb or finger on the front and sides of the shoe.
- Buy your shoes/boots based on the way they feel, not by size:
- You should be able to move your toes comfortably
- There should be a space the width of your thumb nail between your longest toe and the end of the shoe.
- The heel should fit comfortably, with minimal slippage.
- The ball of your foot should fit comfortably into the widest part of the shoe/boot without feeling tight or pinched.
- You should not feel any rubbing or chafing. Remember that your feet tend to get larger from the exertion of daily activities, so make sure there is sufficient room for them to expand and still go through their full range of motion. If possible, shop for shoes near the end of the day, when your feet are larger
- If a doctor or foot specialist provided a prescription for your shoes/boots, always follow his or her requirements and confirm the proper fit on your next visit to the office.
- Remember: Your clinically-tested padded socks, shoes/boots and any inserts or orthotics should feel comfortable from the very first day. This ensures that the integrated fitting “system’ is working properly and providing maximum foot protection and comfort.
