We all have different levels of foot sensitivity, so tyfo come in a range with soft, medium and strong levels of stimulation.

You can build stronger and more efficient muscles & tendons by changing the level of stimulation each day. This means if you buy a soft and medium pair you can influence how your body feels and recover much faster.

It goes without saying that everyone is different, and which model you prefer is a very personal choice that depends on your own physiology such as foot shape and foot strength.

Typically we suggest you start with our softest models (MA3 or MA5) but some people prefer the higher stimulation of our MA4 + MA6 models. Typically our users end up owning multiple types to suit their activity, footwear and level of stimulation they are looking for as they all provide similar yet different sensations at different intensity levels.

We recommend buying one size below your standard sports shoe or walking boot size to ensure a consistent fit.

Yes, our Muscle Activators fit most casual and athletic shoes - narrow or tight fitting shoes (eg: knit uppers or leather dress shoes) tend to cause the most fit issues but varies by brand. We recommend buying one size smaller than your usual shoe size to ensure a better fit.
For a perfect fit we recommend using our tyfo footwear which have been specifically designed for a precise fit with our range of Muscle Activators for maximum performance & benefit.

Yes, you should remove any insoles from your existing footwear before fitting your tyfo Muscle Activators wherever possible as they may interefere with the fit and function of the tyfo product. Indeed it is preferable to use our product in footwear with removable insoles or ample room inside as "Doubling up" on insoles inside your shoes can reduce the room available for your feet.

If the issue is length, consider trimming 1-2mm from the toe or going a size down. If width, perhaps a narrower model may suit. If using our narrowest models & length is not an issue then unfortunately the shoe is unlikely to be suitable for tyfo Muscle Activators eg: slim leather dress shoes

Yes, but only a few millimetres around the toe area to assist in fitting your footwear of choice. More than 1-2mm and you should consider a size down. Please note we can not accept returns of trimmed Muscle Activators.

Yes! tyfos are unique as they activate and stimulate the feet and whole muscle chain, which is something that your Orthotics cannot do. tyfos will strengthen your muscles and tendons, so they should be worn in alternation with your prescribed orthotics.

NOTE: Do not place tyfo Muscle Activators or Orthotics together in the same shoe - use one or the other and rotate your usage.


tyfo is not just another insole. tyfo is a unique concept based on emerging science of the foot and body's fascial network over the past 20 years.

Your foot is a major sensory organ. By using strategically placed activations points designed to stimulate mechanoreceptors buried deep within the foot, we activate dormant muscles and increase sensory feedback to your central nervous system, improving proprioception and providing more input with every step.

Wearing tyfos for your daily activities provides training for your neuromuscular system, building a strong & healthy muscule chain. Its training that doesn't feel like training!

Everyone can benefit from our Muscle Activators for everyday movement since they offer such a wide variety of benefits. Common examples include:

Youth: early intervention during the growth spurt phase can prevent fallen arches, improving foundational strength & general coordination through the feet.

Athletes: the feet are the foundation of all human movement. Our unique Muscle Activators strengthen your feet and retrain your kinetic chain so you become more glute dominant. Testing with our own athletes and consumers has shown time & again that prolonged use of tyfo Muscle Activators lead to some incredible results - check our Test Results page for some examples.

Workers: long periods on your feet not only make your feet feel tired, but your entire body and even mind. tyfo Muscle Activators provide a unque, energising sensation with every step. Whether you wear them all day at work or use them when you get home to rejuvinate your tired feet, tyfo Muscle Activators will change the way you feel.

Injured: lower limb injuries of all kinds place undue stress and loading onto other parts of the body, and can often create misalignment and imbalance in your posture even after rehabilitation, leading to pain in other areas. Your feet are the basis of all your movement so by strengthening them and giving you strong foundations, you can relieve & improve seemingly unrelated issues related further up the kinetic chain. From improving flexion after ACL injuries, to relieving hip and lower back pain by improving your glute loading, we have seen some incredible results for many kinds of injuries and ages. Check out our Injuries, Pain & Conditions page for more information.

Infirm: many people suffering from prolonged issues such as plantar fasciitis, shin splints, knee/hip issues and even non-specific back & neck pain have seen life changing results from using tyfo Muscle Activators. By building strong foundations (your feet!) and improving the way your entire body loads itself from the ground up, we have provided relief to countless individuals. Check out our testimonials page for some examples.

Eldery: as we age a multitude of issues can arise, many of them movement and balance related. tyfo Muscle Activators provide an energising platform that strengthens you with every step, whilst the increased sensory feedback turbocharges your body's 6th sense "proprioception", which is intrinsicly linked to your bodies sense of balance and movement. Reduce the chance of slips and falls with tyfo by your side!



The initial activation happens immediately, however to gain the full benefits takes time. You don’t get strong muscles the day after you hit the gym, and so it is with your tyfo Muscle Activators.

Every foot and every person is different, so how long it takes you to adjust varies from as little as a few hours to as long as a few weeks – listen to your feet and go at a pace that suits you. By the time you are able to wear them all day you will have fully activated your feet and retrained your kinetic chain for improved posture, movement and efficiency.

The vast majority of our users love the new sensation we provide right away, however for a small percentage - especially those with flat feet - some initial discomfort/adjustment period can be experienced.

In your first wear session we recommend only wearing for an initial 20-30mins before waiting a few hours or till the next day, then roughly doubling the wear time each session thereafter. This is because you will be activating muscles in your feet that may have been dormant, weak or underworked for a long time and this is where you may experience some mild discomfort.

If you experience any discomfort then stop, give your feet a rest, then return and increase the next day. Like going to the gym, you will see benefits over time when you stick with it. Usually those who experience the most initial discomfort stand the most to benefit since it is a sign of weak feet.

Yes! People with flat feet usually stand the most to benefit from tyfo, but will also take the longest time to adjust and may experience a little more discomfort early on.
Flat feet take the longest time to adust as the feet need to be restructured and the collapsed arch muscles & tendons will need more time to strengthen and adapt back to their original/intended form.
Over time your arch should start to rebuild it's natural shape. The arch acts as a natrual sprinboard and load bearing support for the body, so enhancing it is just one of the ways tyfo improves your performance.

Yes, you should continue to wear both Muscle Activators to ensure your body properly aligns. Most people are dominant on one side of their body and so it is not uncommon for one foot to take longer to adjust than the other - stick with it, but go at a pace that suits your less dominant foot.

tyfo Muscle Activators can be used for all kinds of sport or activities on land. We do however recommend going through the initial adjustment and break-in period during your down-time (1-6 weeks, depending on the individual) before engaging in any vigorous activities with your tyfo Muscle Activators fitted. Check out our Boost Your Activity page to see how tyfo can benefit you in your chosen sport or activity.


tyfo Muscle Activators can be cleaned using neutral soap and then aired to dry completely. Products containing any solvents or alcohol as ingredients (including as propellants) are not recommended as they may cosmetically damage the product however should not affect overall performance. DO NOT MACHINE DRY.

Unlike most other brands of insoles which use various types of foam which compresses & breaks down over time, tyfo uses durable polyurethane which will retain its shape and performance properties for many years to come.
Prolonged use may see some cracking around the heel activation points, however the overall performance should remain relatively unaffected.
Variable factors such as weight and intensity of usage may shorten the lifespan, but we are confident it will last longer than any other insoles out there under comparable conditions.
