So, you’re ready to dial in your cycling setup and unleash some serious power? Awesome! One often-overlooked aspect of achieving optimal performance and comfort on the bike is the proper installation of your cycling cleats, and sometimes, that involves using shims. Cleat shims are thin pieces of material, typically plastic or metal, that are placed between your cycling shoe and the cleat itself. They’re like little problem-solvers, addressing common issues like leg length discrepancies, foot alignment problems, and even helping to fine-tune your cleat position for maximum efficiency. Without them, you might be leaving valuable watts on the table, or worse, risking injury.
This guide will walk you through everything you need to know about installing cycling cleat shims. We’ll cover why you might need them, the different types available, and, of course, a detailed step-by-step installation process. Whether you’re a seasoned cyclist or just starting out, understanding cleat shims can significantly improve your riding experience. Get ready to optimize your power transfer and say goodbye to discomfort!
Why Use Cycling Cleat Shims?
Before we dive into the how-to, let’s explore the ‘why.’ Understanding the reasons for using cleat shims will help you determine if they’re right for you and your cycling needs.
Addressing Leg Length Discrepancies
One of the most common reasons for using shims is to compensate for leg length discrepancies (LLD). Many cyclists have one leg slightly shorter than the other. Even a small difference can lead to imbalances, causing discomfort, inefficient pedaling, and potentially even injuries. Shims can be used to raise the cleat on the shorter leg, effectively equalizing the leg lengths during the pedal stroke.
Correcting Foot Alignment Issues
Our feet aren’t always perfectly aligned. Some cyclists may have a tendency to pronate (feet roll inward) or supinate (feet roll outward). Shims can help correct these alignment issues by allowing you to adjust the angle of your cleat relative to your shoe. This can improve comfort, reduce stress on your knees and ankles, and enhance power transfer.
Fine-Tuning Cleat Position
Even if you don’t have LLD or significant alignment issues, shims can be used to fine-tune your cleat position. By adding or removing shims, you can subtly adjust the height of your cleat, influencing your foot’s position relative to the pedal axle. This can help you find the most efficient and comfortable pedaling position.
Preventing Hotspots and Pressure Points
By optimizing your cleat position and foot alignment, shims can help prevent hotspots and pressure points on the soles of your feet. This is especially important for long rides, where even small discomforts can become major issues. Shims can help distribute pressure more evenly across your foot.
Types of Cycling Cleat Shims
Not all shims are created equal. Different types of shims are designed for specific purposes. Knowing the differences will help you choose the right ones for your needs.
Standard Cleat Shims
These are the most common type of shims. They are typically thin, flat pieces of plastic or metal that are placed between the cleat and the shoe. They are available in various thicknesses and can be used to raise the cleat by a small amount.
Heel Wedges
Heel wedges are designed to address foot alignment issues. They are thicker at one end, creating a wedge shape that angles your heel inward or outward. This can help correct pronation or supination. (See Also: Do You Need to Grease Bolts on Cycling Shoe Cleats?)
Forefoot Wedges
Forefoot wedges, similar to heel wedges, are designed to address foot alignment issues but are placed under the ball of the foot. They help angle the forefoot to achieve optimal alignment with the pedal.
Cleat Wedges
Cleat wedges are designed to adjust the angle of the cleat relative to the shoe. This can be used to fine-tune foot alignment, and they are often used in conjunction with other types of shims.
Specialty Shims
Some manufacturers offer specialty shims designed for specific cleat systems or to address unique needs, such as those that provide additional arch support or address specific foot conditions.
Tools and Materials You’ll Need
Before you start, gather the necessary tools and materials. Having everything ready will make the installation process smoother.
- Cycling Shoes: Your cycling shoes are, of course, essential.
- Cycling Cleats: Make sure you have the correct cleats for your pedal system.
- Cleat Shims: Choose the appropriate type and thickness of shims based on your needs.
- Allen Wrenches: You’ll need the correct size Allen wrench for your cleat bolts.
- Torque Wrench (Recommended): A torque wrench helps you tighten the cleat bolts to the manufacturer’s specified torque, preventing over-tightening or under-tightening.
- Grease: A small amount of grease can prevent corrosion and make adjusting the cleats easier.
- Ruler or Calipers: Useful for measuring leg length discrepancies or adjusting cleat position.
- Marker: A marker can be helpful for marking the original cleat position.
- Optional: A cleat alignment tool can help with precise cleat positioning.
Step-by-Step Guide to Installing Cycling Cleat Shims
Now, let’s get down to the actual installation. Follow these steps carefully for optimal results.
Step 1: Preparation and Assessment
Before you start, take some time to assess your needs. Consider the following:
- Identify the Problem: Are you addressing leg length discrepancies, foot alignment issues, or simply fine-tuning your cleat position?
- Measure Leg Length (If Applicable): If you suspect LLD, measure your leg lengths. You can do this by having someone measure from your hip bone (ASIS) to your medial malleolus (inner ankle bone).
- Assess Foot Alignment: Observe your foot position while pedaling. Do your feet tend to roll inward or outward?
- Mark the Existing Cleat Position: Before removing your cleats, use a marker to trace around their current position on your shoe. This will give you a reference point for reinstalling them.
Step 2: Remove the Existing Cleats
Using the appropriate Allen wrench, loosen the cleat bolts. Don’t remove them completely yet. Once the bolts are loose, carefully remove the cleats from your shoes.
Important: If your cleats are new, you may want to clean the area around the cleat bolt holes. This ensures that the shims sit flush against the shoe.
Step 3: Install the Shims
Place the shims between the cleat and the shoe. The number and type of shims you use will depend on your needs. If you are addressing LLD, you will likely use shims on the shorter leg. If you are correcting foot alignment, you may use heel or forefoot wedges. Ensure the shims are properly aligned with the cleat bolt holes. (See Also: What Is the Smallest Baseball Cleats?

Step 4: Reinstall the Cleats
Carefully align the cleats with the bolt holes in the shims. If you marked the original position, use those marks as a guide. If not, start with a neutral position and make adjustments later. Insert the cleat bolts through the cleats and shims.
Step 5: Tighten the Cleat Bolts
Using your Allen wrench, begin tightening the cleat bolts. Do not tighten them completely at this stage. Leave them loose enough so that you can still adjust the cleat position. If you have a torque wrench, use it to tighten the bolts to the manufacturer’s recommended torque specification. This is crucial for preventing damage to your shoes and cleats.
Step 6: Adjust Cleat Position (optional)
If you’re not sure about the cleat position, you might want to adjust it now. This involves moving the cleat forward or backward, or rotating it slightly. The goal is to find the position that feels most comfortable and efficient. You can use the following general guidelines:
- Fore/Aft Adjustment: Adjusting the cleat forward or backward influences the position of your foot relative to the pedal axle. Moving the cleat forward may be better for climbing, while moving it backward may provide more power on the flats.
- Rotational Adjustment: Rotating the cleat adjusts the angle of your foot on the pedal. This is especially important for addressing foot alignment issues.
Step 7: Test Ride and Fine-Tune
Once you’ve installed the shims and tightened the cleat bolts, it’s time for a test ride. Go for a short ride and pay attention to how your feet and legs feel. Are there any pressure points or discomfort? Is your pedaling smooth and efficient?
If you experience any issues, make small adjustments to your cleat position or shim configuration. This may involve adding or removing shims, or adjusting the cleat’s fore/aft or rotational position. Keep making adjustments until you find the perfect fit. This process may take a few rides, so be patient.
Step 8: Final Tightening and Maintenance
Once you’ve found the optimal cleat position and are happy with the fit, tighten the cleat bolts to the manufacturer’s recommended torque specification. Regularly check the cleat bolts for tightness, especially after riding in wet or muddy conditions. Also, clean your cleats and shoes regularly to remove dirt and debris.
