Which Aetrex Lynco Orthotic Should I Choose? Take our two-question test now!

Aetrex Lynco L405 orthotic

Let’s start with the Aetrex Lynco numbering system.

All orthotics from Aetrex are given a three or four-digit item number that starts with the letter “L” (L400, L2205, L2225, etc).

The digit on the far right of this number is always either a “0” or a “5”. Very simply, “0” is given to orthotics that do not have a metatarsal pad, while a “5” is given to orthotics that have a metatarsal pad. So, for example, the L2200 does not have a metatarsal pad, and the L2205 does.

Next is the digit that is second from the right (in the tens place, if you will). There are two possible numbers in this place, “0” or “2”. A “0” in this place is given to orthotics that do not have a heel post, while a “2” in this place is given to those that have a heel post. A “heel post” is defined as a small build up of material on the inside of the heel to help control over-pronation (an inward roll of the foot that can lead to plantar fasciitis, misalignments in the ankles, knees, hips and back, and many other unwanted ailments).

Finally, we have the digit or double digits that are on the left of the item number (4, 6, 8, and 22 are examples). These digits tell you the series of orthotics that you are looking at. The series of the orthotic can give you information about the materials used in construction, cushioning, thickness, and intended use. For example, all orthotics that start with a “22” are part of the 2200 series, which offers soft memory foam cushioning and is designed for all-day comfort.

So, putting this all together, a L2205 orthotic will have a metatarsal pad (the “5” on the far right in the ones place), will not have a heel post (the “0” in the second place from the right), and will feature memory foam for cushioning and be intended for everyday use (characteristics of the 2200 series – the “22” on the far left of the item number).

One more example: A L420 orthotic will not have a metatarsal pad (the “0” on the far right in the ones place), will have a heel post (the “2” in the second place from the right), and will feature extremely soft cushioning but a slightly lower profile than the 2200 series and will be intended for general physical activities (characteristics of the 400 series – the “4” on the far left of the item number).


Now you’re an Aetrex Lynco identification expert, but how do we put this knowledge to practical use? Below are some of the most common foot ailments and our recommendations for specific Aetrex Lynco orthotics for each:


Plantar Fasciitis PainPlantar Fasciitis: While any Aetrex Lynco orthotic will offer some plantar fasciitis pain relief versus walking in a non-supportive pair of shoes, the 2200 series, with its supportive yet soft and soothing memory foam, is an excellent choice. If your plantar fasciitis is caused by over-pronation (an inward roll of the medial arch and can over elongate and strain the plantar fascia tissue on the bottom of the foot), then the L2220 is an excellent choice, as this model features a heel post that will help to naturally align your heel and arch and prevent over-pronation. To learn about other recommendations for eliminating plantar fasciitis pain, click here.

Metatarsalgia: This is a general term given to a variety of conditions that cause pain in the ball of the foot. As such, the key to metatarsalgia relief, from an orthotic standpoint, is a metatarsal pad to support the metatarsal arch and take pressure off of the ball of the foot. So, for metatarsalgia, we recommend an orthotic such as the L405, L2205, or L105 that all feature a metatarsal pad. The series that you choose depends entirely on your end use. For example, if you’re looking for an orthotic for sneakers for running and walking, the L405 is a fine choice, while if you need something for a slim fitting business shoe, the L105 is a great place to start. To learn more about metatarsalgia, click here.

Morton’s Neuroma: Similar to metatarsalgia, this is all about relieving pressure on the ball of the foot, so a metatarsal pad is highly recommended for Morton’s neuroma relief.

Neuropathy: The causes of neuropathy are far ranging and can vary widely from one individual to another, so choosing an orthotic for this condition can be a deeply personal choice, however we have found that a softer, cushioned orthotic can help to ease neuopathy pain. The 600 series and 2200 series, with their extra plush cushioning, are well worth a look if you suffer from neuropathy.


Whether or not you are suffering from a debilitating foot condition or your work shoes are just in need of a bit more comfort and support, Aetrex Lynco orthotics are a top choice for relief. We hope you find this guide useful!
