Spenco RX Orthotic Arch Support Insoles

The Spenco RX Orthotic Arch Support Insoles are designed for individuals with flat, low, or fallen arches. They can also help to reduce pronation and supination for improved foot stability, and can be purchased as either full-length or 3/4-length insoles.

What's Included?

• 1 x Pair of Orthotic Arch Support Insoles

The Orthotic Arch Support Insoles are available as either full length or 3/4-length. Your required style can be selected from the drop-down menu at the top of the page.

Which Size Do I Need?

The RX Orthotic Arch Support Insoles are available in a range of sizes, helping to ensure you can find the most snug and comfortable fit for your footwear. The following sizes are available, and can be selected from the drop-down menu at the top of the page.

Please note that the insoles are also available for shoe sizes under Size 4 and over Size 11 while stocks last.

Who Can Use the Spenco RX Insoles?

Designed for optimal support underfoot, the Spenco RX Orthotics are ideal for individuals with low, flat, or flattened arches. This is particularly useful if you suffer from plantar fasciitis or general arch pain or strain. They also help to reduce pronation or overpronation, improving the stability of your foot, and in turn reducing any associated pain.

Should I Choose the Full Or 3/4-Length Insoles?

The insoles are available in two styles to ensure the most comfortable fit in a range of shoe types. The full-length orthotics are ideal for wearing in most footwear, including casual shoes, sports shoes, and boots. The 3/4-length insoles are better for shoes with narrower toes where a full-length insole might not otherwise fit.

How Do I Adjust the Insoles?

If you find that the orthotic insoles are not providing the right support, they can be placed in boiling water for two minutes and then bent into the desired shape. Hands should be protected with gloves or a towel during this process.

SpenCore for Impact Absorption

The Spenco Orthotic Arch Support Insoles feature a special layer of SpenCore material that is specifically designed to absorb shock and impact, in turn providing optimal comfort underfoot. The Silpure antimicrobial fabric also helps to prevent blisters and control odours, helping to keep feet both fresh and free from pain.

How Do I Use the Orthotic Arch Support Insoles?

To use the RX inserts, place them in your shoes with the green side facing upwards. If the insoles are a little too big, they can be trimmed down to size.

How Thick Are the Orthotic Arch Support Insoles?

The insoles have an arch height of 25.8mm (1"). The heel thickness measures 6.29mm (1/4").

How Do I Wash the Orthotic Arch Support Inserts?

The Spenco inserts can be hand washed in warm water. They must then be air dried before use.

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.
