Shock Doctor Active Impact Insole

The Shock Doctor Active Impact Insole is designed exclusively for long runs, hikes and harder surfaces, making it ideal for marathons and fell walking. By dispersing the impacts hard surfaces like tarmac and hard dirt have on your feet, the Shock Doctor Active Impact Insole can seriously improve your run.

Absorb Shocks

The Adaptive Arch Technology found in the Shock Doctor Active Impact Insole means the insole can adapt itself to your foot shape, offering the best possible shock absorption.

The Shock Doctor Court Insole's Heel and Mid-Foot ShockDome also helps to absorb these shocks, and stops them transferring to your knees and hips, both preventing injury and making you more stable.

Increase Stability

The Butterfly Control Bar on the Shock Doctor Active Impact Insole reduces the amount your feet roll while you run. This makes your feet more stable and gives you a more secure stride, and also keeps over-pronation (over-rotating of the foot) under control., This means your run and walk becomes much safer and puts less strain on your ankle.

Reduce Foot Fatigue

Thanks to the Full-Foot Shock Absorbing Foam, the Shock Doctor Active Impact Insole helps slow down the foot and ankle fatigue you can experience after walking or running for a while. The benefit of this is clear; by reducing fatigue you can walk or run for longer than ever, which means your hikes can be more beautiful and your runs can be more demanding.

Protect From Injury

By keeping your foot stable and reducing shocks, the Shock Doctor Active Impact Insole can help prevent a foot injury from developing. Foot injuries like plantar fasciitis can put you out of action for months, which for runners means not only will you not be able to improve your run but without continual practice there's a very real chance your ability to run would get worse. That's why you should do everything to stave off injury, and why the Shock Doctor Active Impact Insole does exactly that.

The Heel and Mid-Foot ShockDome on the Shock Doctor Active Impact Insole can even help relive plantar fasciitis, making it a great shoe insole for sidelined runners who want to get back on the track.

Our Guide to Finding the Perfect Size and Fit

Using Your Shoe Size

For most of our insoles, the easiest way to find the best size for you is to go off of your current shoe size. The majority of our insoles are available in a range of sizes and you can simply select the size that best fits your existing shoes.

Please be aware that, as with shoes, there can be slight variations in the size of insoles. For example a size 8 of one brand might not be exactly the same size and width as the size 8 of another. To help account for these discrepancies, a number of our insoles include dimensions to help you ensure you're getting the right size.

Measuring Your Current Insoles

While using your shoe size to find your best size is a good guide, it is not always foolproof. If you want to guarantee that your insole fit your shoes as closely as possible, we recommend measuring your existing insole and using this as a guide to your size.

To do this, please follow the steps outlined below:

1. Remove the existing insole from the shoes you wish to use your new insoles with (please note that not all insoles are removable)
2. Measure the insoles at their longest and widest points (see the below diagram for an idea of where this will be
3. Match the measurements to the dimensions of the insoles listed, and choose the size that best fits your results

Where Can I Find the Dimensions?

The dimensions for insoles can be found on the "Product Details" tab (please see below) and are usually found in the sizing section of the listing, in a table. Please be aware that not all products currently have the dimensions listed.

The dimensions of insoles can usually be found on the "Product Details" tab

What If There Are No Dimensions Listed?

If you do not see the dimensions listed on the Product Details tab, please fill in the form below and we will work to get the relevant information as quickly as possible. We will email you once we have the information that you have requested.

Trimming Your Insoles to Fit

To get the ultimate level of fit from your insoles, you can trim them to make a small adjustment. To trim your insoles, simply follow the steps below:

1. Remove your existing insoles from your shoes
2. Line up your existing and new insoles at the heel
3. Trace the outline of the insoles against the new pair at the toe end (see the image below for an example)
4. Carefully cut along the traced line
5. Your insoles should now fit your shoes better

Carefully trace the outline of your insole

Please note that not all insoles are suitable for trimming. Most insoles are unsuitable for return once they have been trimmed to fit; we recommend bearing this in mind prior to trimming.
