How to Choose the Right CURREX Arch Profile
Choosing the right insole starts with understanding your feet. You might know your shoe size down to the half-size and have strong opinions about your favorite running shoes, cleats, or court shoes, but do you know your arch profile?
Arch height is one of the factors that can influence how an insole fits and feels beneath your foot. Two people wearing the same size shoe can have very different arch profiles, which is why CURREX insoles are available in high, medium, and low.
The goal isn't to force your foot into a certain position or choose the highest level of support possible. It's to find an arch profile that works with how your foot is built and moves. Combined with CURREX Dynamic Arch Technology (DAT), the right profile provides adaptable support designed to move with you.
What Is Arch Height?
Your foot contains 26 bones connected by joints, muscles, tendons, and ligaments. Together, these structures create multiple arches that change shape as your foot loads and unloads during movement. When people talk about "arch height," they're generally referring to the height and shape of the medial longitudinal arch; the visible curve running along the inside of the foot from the heel toward the forefoot.
Arch height varies naturally from person to person. Some feet have relatively little space beneath the arch when standing. Others have a more pronounced curve. Many fall somewhere in between. That's where the familiar low, medium, and high categories come from. But there's an important detail: your arch isn't a fixed structure that stays exactly the same throughout every step. It changes as you stand, walk, run, jump, and load your foot. That's one reason CURREX focuses on Dynamic Arch Technology, rather than treating the foot like something that needs to be held rigidly in one position.
Why Your CURREX Arch Profile Matters
Think about where an insole sits: directly underneath your foot, inside a shoe that may already have a very specific shape and purpose. If the arch profile doesn't match your foot well, you'll probably notice.
An arch that feels too prominent may create unwanted pressure beneath the foot. A profile that doesn't make enough contact may not provide the comfortable support you're looking for. The right match should feel present without becoming distracting. CURREX offers different arch profiles to create a more individual fit while maintaining the movement-focused characteristics of each activity-specific insole. And that's an important distinction: arch profile and activity are two different parts of choosing your CURREX insole.
First, you choose the CURREX model designed for your activity such as RUNPRO™, CLEATPRO™, PICKLEBALLPRO™, BASKETBALLPRO™, GOLFPRO™, HIKEPRO™, or SUPPORTSTP™. Then, you select the appropriate arch profile.
A runner with a Low Arch Profile and a runner with a High Arch Profile can both choose RUNPRO™, for example. They're doing the same activity, but their feet don't necessarily need the same profile beneath them.
CURREX High, Medium, and Low Arch Profiles Explained
Low Arch Profile
A low arch profile is designed for feet with a lower arch height. When standing, these feet generally have more contact between the midfoot and the ground. The CURREX low provides support shaped for that lower arch rather than placing an unnecessarily prominent structure beneath the foot.
The important word here is match. Having a low arch doesn't mean you need to "build" a higher one with your insole. CURREX is designed to support natural movement, not force every foot toward the same shape.
Medium Arch Profile
The medium arch profile is designed for feet that fall toward the middle of the arch-height range. If you have a visible curve along the inside of your foot while standing but don't have especially low or pronounced arches, you may fall into this category. Don't automatically choose medium because it sounds like the safe middle option, though. Determining your actual profile gives you a better starting point than guessing.
High Arch Profile
A high arch profile is designed for feet with a more pronounced arch and less contact through the midfoot while standing. The shape provides support designed to better match the space beneath a higher arch. Again, "high" doesn't mean more support is better. It means the geometry of the profile is designed for a higher arch. Choosing high simply because you want maximum support can create a mismatch if your foot actually has a medium or low arch.
How to Measure the Arch of Your Foot
If you're wondering how to measure the arch of your foot, you have a few options. Some are more precise than others. One of the easiest places to start is the CURREX at-home Fitting Guide, which is designed specifically to help determine the appropriate arch type.
Your arch should be evaluated while you're weight-bearing because your foot changes shape under load. That's more useful than looking at your foot while sitting down and trying to estimate how high the arch appears. For the most accurate CURREX recommendation, follow the CURREX Insole Finder which will give you a more personalized recommendation.
How Should the Right Arch Profile Feel?
Once you've identified your profile, your feet get the final vote. Proper arch support should create comfortable contact beneath the foot. You should be aware that the insole is supporting your arch, but it shouldn't feel like you're standing on a hard bump. The real test also isn't the first 30 seconds after putting your shoes on. Walk around, spend time in the footwear the way you normally would. Pay attention to how the support feels once your foot is moving and the shoe is working under real conditions.
A well-matched profile should work with your movement rather than constantly reminding you that it's there. If you're experiencing concentrated pressure directly beneath the arch, don't assume that's what "good support" is supposed to feel like. More noticeable isn't necessarily better.
Your Arch Profile Doesn't Tell You Everything About Your Foot
This is where choosing insoles gets more interesting. Arch height is useful, but it isn't a complete description of how your foot functions. People with similar-looking arches may not necessarily move in exactly the same way, and that's another reason CURREX doesn't stop at arch height.
Dynamic Arch Technology is designed around movement. Instead of simply placing a static arch shape beneath the foot, DAT provides adaptable support that works with natural motion. Combined with the fully decoupled heel cup and activity-specific construction, the design recognizes something athletes already know intuitively: your feet aren't standing still when you're performing.
Choose Your Activity Before Your Arch Profile
Knowing how to measure your arch height solves only one part of the equation. The next question is: What are you doing in your shoes?
CURREX designs activity-specific insoles because different sports place different demands on your feet and footwear. Running involves thousands of repetitive forward movements. Cleated sports combine acceleration, cutting, and rotation inside narrow footwear. Pickleball and basketball demand rapid multidirectional movement. Hiking adds changing terrain and long periods on your feet. Golf combines walking with repeated rotational movement.
Your selection process should therefore look like this:
- Choose your activity. Start with the CURREX insole designed for the way you move.
- Determine your arch profile. Identify whether you need the High, Medium, or Low Arch Profile.
- Match your shoe size. Select the appropriate insole size for your footwear.
- Evaluate the fit while moving. Make sure your arch feels comfortably supported and the insole works naturally inside your shoe.
Can Your Arch Profile Change?
Your feet aren't necessarily identical throughout your entire life. Age, activity, changes in body composition, pregnancy, and other factors can influence foot shape and dimensions over time.
That doesn't mean you need to constantly remeasure your arch. But the profile you selected years ago shouldn't automatically be treated as permanent if your feet or footwear experience now feels different. It's worth checking again when replacing older insoles, changing shoe sizes, returning to activity after a long break, or moving into a different type of sport or footwear.
Growing athletes deserve particular attention. Kids and teenagers can change shoe sizes quickly, so parents should regularly reevaluate footwear and insole fit rather than assuming last season's setup still works.
Don't Forget That the Insole Has to Fit the Shoe
The perfect arch profile isn't useful if the insole doesn't work inside your footwear. A running shoe, soccer cleat, hiking boot, basketball shoe, and everyday sneaker all have different internal shapes and amounts of available space. That's why CURREX insoles aren't simply differentiated by arch profile, they're designed around specific activities and footwear.
CLEATPRO™, for example, is built for the limited space inside cleated footwear, while RUNPRO™ is engineered around running movement and running shoes. The insole should complete the shoe, not compete with it. When installing CURREX insoles, remove the existing factory liner when appropriate and make sure the replacement sits flat inside the shoe without bunching or altering the intended fit.
The Right Profile Is the One That Lets You Keep Moving
CURREX insoles are designed by German sports scientists to bring together arch-specific fit, Dynamic Arch Technology, Dual Layer Cushioning, and activity-specific engineering. The result is support designed around something more useful than simply holding your foot in place: helping your feet move naturally and comfortably inside the shoes you already use.
CURREX Arch Profile FAQs
Q: How do I determine my arch height?
A: Use the CURREX Fitting Guide or Insole Finder to determine which arch profile you have. Evaluating the foot while weight-bearing provides more useful information than simply looking at the arch while seated.
Q: Should I choose a higher arch profile for more support?
A: No, the different arch profiles refer to the shape and height of the arch profile, not increasing levels of support. Choose the profile that best matches your foot rather than assuming higher means better.
Q: What should proper arch support feel like?
A: Proper arch support should create comfortable contact beneath your foot without a concentrated or distracting pressure point. The support should continue to feel comfortable while you're moving in your normal activity.
Q: Do I need a different CURREX Arch Profile for different sports?
A: Your arch profile is based on your foot, while the CURREX model is based on your activity. For example, the same athlete may use the same arch profile in RUNPRO™ for running and CLEATPRO™ for cleated sports while benefiting from each product's activity-specific design.
