How Are Shin Guards Supposed to Fit?

When considering the fit of MMA shin guards, it’s essential to understand their role in a combat sport involving high-impact striking and grappling. MMA, or Mixed Martial Arts, is a full-contact sport incorporating techniques from various martial arts and combat sports. Shin guards in MMA are designed to protect both the wearer and their sparring partner from serious injury during training sessions. The fit of these guards is crucial for effective protection and performance.

Understanding the Importance of Proper Fit

  1. Protection: The primary purpose of shin guards is to protect the shin bone, a sensitive and injury-prone area, from the impact of kicks and blocks. A well-fitted guard will distribute the force of impact over a larger area, reducing the risk of fractures or severe bruising.
  2. Mobility: MMA involves a lot of movement, including kicks, pivots, and grappling. A shin guard that fits properly will allow a full range of motion without slipping or causing discomfort.
  3. Comfort: Training sessions can be long and intense. Shin guards that are too tight can impede blood circulation, while those that are too loose can chafe and distract the fighter.
  4. Sparring Safety: In sparring, both fighters’ safety is paramount. Shin guards that fit well ensure that both the wearer and their partner are protected during practice bouts.

Key Aspects of Fit

  1. Size: Shin guards come in various sizes. To choose the right size, measure the length of your shin from just below the knee to above the ankle. Most manufacturers provide a size chart based on these measurements.
  2. Width Fit: The width of the shin guard is also important. It should be snug but not overly tight. There should be no gaping spaces between the guard and your shin.
  3. Strapping System: The strapping system helps secure the guard in place. It usually consists of Velcro straps that wrap around the back of the calf. Ensure these straps are adjustable for a customized fit.
  4. Ankle Support: Some shin guards come with additional ankle support. This can be beneficial, especially for fighters with previous ankle injuries.
  5. Material and Padding: The material should be durable yet flexible. Foam padding is common, but the density and thickness can vary. Thicker padding offers more protection but can be heavier and less comfortable.

Fitting Process

  1. Wear Appropriate Gear: When trying on shin guards, wear the socks and any additional gear (like compression sleeves) you normally wear during training.
  2. Positioning: The top of the guard should start just below the knee cap and extend down to cover the shin. It should not restrict knee movement or extend too far down to the foot.
  3. Adjust the Straps: Secure the straps so that the guard is snug but not cutting off circulation. Walk around and throw a few kicks to ensure they stay in place.
  4. Check for Slippage: During movement, the guards should stay in place. If they slide down or twist, they’re either too big or not properly secured.
  5. Comfort Assessment: Practice some typical training moves. The guards should not pinch, rub, or cause any discomfort.

Maintenance and Longevity

  1. Cleaning: Regularly clean the shin guards according to the manufacturer’s instructions to prevent the buildup of bacteria and odor.
  2. Inspection: Regularly inspect the guards for signs of wear and tear. Compromised guards can offer reduced protection.
  3. Storage: Store the shin guards in a cool, dry place away from direct sunlight to prevent the material from degrading.


In MMA, shin guards are a vital piece of equipment. The correct fit is crucial for protection, comfort, and performance. Take the time to find the right size, ensure a snug yet comfortable fit, and maintain your guards well. Remember, the right shin guards can significantly affect your training effectiveness and safety.
