Why It Matters

Your Movement
Tells the Full Story

How you move is unique to you. Small imbalances in your gait, invisible to the naked eye, accumulate over time and lead to injury, discomfort, and reduced performance. Whether you are training for a marathon, walking for fitness, or simply struggling with persistent foot pain, a professional biomechanical assessment is the most accurate way to understand what is happening and how to address it.

  • 🦶
    Identify Hidden Injury Risks

    Our podiatry-based assessment reveals alignment issues, overpronation, and movement patterns linked to common running and walking injuries, before they sideline you.

  • 🩺
    Relief for Foot Pain and Discomfort

    From plantar fasciitis and heel pain to flat feet and general foot fatigue, our assessment helps identify the root cause and find footwear that provides genuine, lasting support.

  • 👟
    Find the Right Shoe for You

    Not all shoes are equal. We match your unique biomechanics to footwear that supports and enhances your natural movement, not a generic category off the shelf.

  • 📈
    Move Further, More Comfortably

    Correct biomechanics mean more efficient movement. Reduce energy waste, improve your stride, and protect your joints for the long term.

"More than 50% of runners suffer some form of musculoskeletal injury each year, with the majority attributed to training errors and biomechanical factors."

Alexandra Sports gait analysis consultation with a running specialist in Portsmouth and Christchurch
Step 01
Consultation

We start with you. Your goals, terrain, experience level, and any injury or foot pain history are all discussed. We also examine the wear patterns on your current footwear, which can be a surprisingly revealing window into your gait.

Podiatry-based biomechanical assessment of foot and alignment
Step 02
Biomechanical Assessment

Using podiatry-based clinical tests, we evaluate your alignment, posture, foot movements, joint range of motion, and knee tracking, identifying patterns associated with injury risk and discomfort.

Our Technology

Precision
Foot Mapping

Our 3D foot scanning technology is the gold-standard in foot measurement, used by elite performance labs worldwide. We were among the very first running specialists in the UK to bring it into store, because we believe your feet deserve more than a guess. Your feet are not average. Your measurement should not be either.

📐
True 3D Foot Scanning

Captures the exact geometry of both feet: length, width, volume, and arch height, far beyond the flat 2D tracing used in most shoe shops.

Dynamic Pressure Mapping

Visualises exactly where and how load is distributed across your foot as you move, revealing compensation patterns invisible to the naked eye.

🎯
Slow-Motion Video Analysis

Professional software dissects your gait frame by frame, identifying overpronation, supination, and asymmetries that cause cumulative injury over time.

🤝
Expertise That Goes Beyond the Data

The technology tells us the facts. Our staff know what to do with them. Years of hands-on fitting experience mean we translate your scan data into a shoe that genuinely works for you as an individual.

Custom Insole
Fitting

A great shoe is only part of the picture. For runners, walkers, and anyone dealing with persistent foot discomfort, our custom insole fitting service builds on your gait analysis to create a personalised foundation inside your footwear, addressing specific biomechanical needs that an off-the-shelf insole simply cannot match.

  • Personalised to your biomechanics

    Designed using the data gathered during your gait analysis, targeting your specific foot shape, arch profile, and movement patterns.

  • Reduce pain and prevent injury

    Correct overpronation, supination, and uneven load distribution that contribute to knee, hip, and lower back discomfort.

  • Works in any shoe

    Custom insoles are transferable between footwear, so your investment protects you whether you are on road, trail, or gym floor.

FAQ

Common Questions

Everything you need to know before booking your gait analysis or biomechanical assessment.

Is a gait analysis worth it?

Yes. Running or walking in the wrong footwear will almost always lead to injury and discomfort over time. A 30-minute biomechanical assessment can significantly improve your comfort, reduce your injury risk, and give you confidence in every step.

How much does it cost?

Your gait analysis is free with the purchase of any footwear. A £30 deposit is taken at the time of booking and is deducted from the price of any footwear bought in-store on the day, making the full assessment completely free with purchase.

Can I book an assessment without buying anything?

Absolutely. There is no commitment to purchase. You can book an appointment for our gait analysis and biomechanical assessment with no obligation to buy on the day. Your £30 deposit is simply held until your appointment.

Do I have to book, or can I just walk in?

You are welcome to walk in, but we highly recommend booking in advance. Booked appointments always take priority over walk-ins, so booking guarantees your slot and avoids a wait.

What if I just need advice?

Our team are always happy to help. You can reach us by phone, email, or simply pop into either store and speak with a member of staff. No appointment needed for a quick chat.

Is there such a thing as a normal running gait?

No. Everyone has a unique gait pattern. That is exactly why a personalised biomechanical assessment is so valuable: it looks at your movement specifically, not an assumed average.

How often should I have a gait analysis?

We recommend a new gait analysis every time you purchase a new pair of running shoes, or at least every 8 to 12 months, whichever comes first. Your gait changes over time, so it is worth reassessing regularly rather than assuming the same shoe will always suit you.

Should I stick to the same brand or shoe model?

Not necessarily. Brands update their models regularly and the changes can be significant. Your gait also evolves over time. We recommend reassessing with each new purchase rather than automatically rebuying the same shoe.

How often should I replace my running shoes?

We recommend replacing your running shoes every 300 to 500 miles, or every 10 to 12 months for regular runners, whichever comes first. Worn cushioning can alter your gait and increase injury risk even when shoes still look fine on the outside.

Do new running shoes need breaking in?

There is no fixed mileage for breaking in new shoes, but we recommend easing into them gradually for longer runs. A properly fitted pair should feel comfortable from day one, not painful. If they are not, come back in and we will take another look.

My new shoes are giving me blisters. What should I do?

Your fitted shoes should feel comfortable from the start. Blisters are often a sign of fit, lacing, or sock issues. Come back into either store and speak with a member of staff and we will get to the bottom of it and make sure you leave happy.
