The Reviews

“Now when I take my shoes off at the end of the day I do not have anywhere near the level of discomfort I had in the past and the tingling in my right foot is all but gone. Well done guys, I am sold on them!”

“I have been wearing gel-type inserts for years in all of my athletic shoes and I have never felt this level of comfortable support until using SelectFlex. Over the last couple of years, my right arch has been achy and painful and I’ve had a tingling sensation in my foot and toes. I play tennis five times a week and golf once a week. After putting SelectFlex in my tennis shoes I felt a comfort right away. … Read Full Review Because of the problem I’ve been having with my right foot, I set the right side to level #3 and the left side to level #1. After about a week I adjusted the right side support level back to #2 which is optimal for me. Now when I take my shoes off at the end of the day I do not have anywhere near the level of discomfort I had in the past and the tingling in my right foot is all but gone. Well done guys, I am sold on them!” Read Less

“When I first put SelectFlex into my sneakers I could immediately feel great arch support. They were firm but not hard. I pronate severly on my right side and SelectFlex provides me with great support and a better alignment in my hips. I am a massage therapist and so I am on my feet a lot. I am also a very active person, swimming, playing tennis and taking daily power walks. … Read Full Review I am giving SelectFlex a rating of 5. I have had issues with my right hip, psoas, and lower back due to poor arch support in the past. I have had no pain since using SelectFlex. My arches are well supported aligning my muscles and joints in the correct position. I feel less fatigue and my legs feel energized!” Read Less

5 Stars | John H. (NJ - US)

“My product rating is 5 as SelectFlex provides excellent arch support. I feel more secure in my footing and they are very comfortable. My stride is stronger and longer, and much more comfortable. I have worn gel inserts in the past and they offer very little arch support and don’t last. I also have orthotics from my podiatrist but they are too firm and uncomfortable. … Read Full Review With SelectFlex I feel very strong arch support that is also very comfortable. I found the adjustable feature easy to use and very valuable. I tore ligaments in one ankle twice and one time in my other ankle. And I have fallen arches. So I have the arch support for one ankle firmer than the other which works great for me. I should mention that they did not work well in a firm leather dress shoe but in a softer leather shoe they work great. I plan to start using them in my sneakers as well. I feel so much better walking with SelectFlex which translates into a more comfortable and higher activity level for me. I feel like I’m actually getting into better shape too!” Read Less

“Since wearing SelectFlex the burning sensation I used to have in my heels is gone. I have no more achy feet and I no longer have aches at the back of my legs. I play tennis six days a week for 4-5 hours a day. Prior to using SelectFlex, I struggled to walk after playing tennis. Even getting out of bed in the morning and taking my first steps was painful. Since wearing SelectFlex,… Read Full Review the burning sensation I used to have in my heels is gone. I have no more achy feet and I no longer have aches at the back of my legs. The balls of my feet are no longer tight and sore and my ligaments seem to be more flexible and relieved of their tightness. I find SelectFlex’s “medium” comfort zone to be exactly the correct setting for me.

“Overall I had a very positive experience using SelectFlex. I thought they were very comfortable and they offered a great deal of support under my heels. I felt a noticeable difference in how my heels, legs and back felt after wearing SelectFlex. I am a starting center defender for my college soccer team. I’ve had a long history of lower back issues, including surgery, … Read Full Review but have remained very athletically active today. I felt a noticeable difference in how my heels, legs and back felt after wearing SelectFlex. In the past, my left leg in particular would tend to bother me while running. This stems from my previous back issues. I would get pain in my left foot and lower back. After wearing SelectFlex I began to experience less pain in my feet, legs and lower back. There was just a better sense of support and comfort when running. Please make a narrower version of SelectFlex so I can use them in my soccer cleats!” Read Less

“I have tried various inserts and supports for my shoes and SelectFlex are very clearly the best I have ever used. Your foot feels more stable and the heel strike is very comfortable making my feet less tired. 5 Stars for me! I have been wearing SelectFlex in my Keen walking shoes. I wear these shoes a lot for exercise walking, dog walking … Read Full Review and general use when I am out and about. They have made an already comfortable pair of shoes EXCELLENT! They are brilliant and I can’t wait to try them in my tennis shoes!” Read Less

Frequently Asked Questions

View all FAQs

HOW DOES TURNING THE ADJUSTER ACTUALLY CHANGE ARCH SUPPORT?

Years in development, SelectFlex is breakthrough technology. With each adjustment, our proprietary technology increases or decreases the flexural resistance to support variable arch loads. Think of it as a second arch you control that never gets tired!

HOW WILL SELECTFLEX TECHNOLOGY WORK FOR MY UNIQUE FEET?

One of the most amazing features of SelectFlex Orthotics is that they bio-medically conform to your unique arch geometry within 3 ranges of selectable support. Within each comfort zone (Medium, Firm, X-Firm), your arch will naturally and dynamically seek out the level of support it requires throughout the gait cycle.

HOW DOES SELECTFLEX TECHNOLOGY PROVIDE ENERGY ABSORPTION AND ENERGY RETURN THROUGHOUT THE GAIT CYCLE?

Patented iFlex technology acts like a life-like spring ligament supporting your arch and absorbing downward forces during each and every step of the gait cycle, and then releasing energy back to the foot.

WHICH FOOT AND BODY AILMENTS DOES SELECTFLEX HELP WITH?

Everyone’s experience with SelectFlex will be unique to their specific foot and body conditions, which is why SelectFlex’s adjustability is so important. Proper use of SelectFlex orthotics may help reduce over-pronation and under-supination, flat feet, Plantar Fasciitis, reduce lower back pain, shin splints, as well as sore ankles and knees. Please see our “How It Works” explanation for all the details on how SelectFlex can help your feet, ankles, knees, hips, and back.

DO SELECTFLEX ORTHOTICS COME WITH A GUARANTEE?

We are so confident in SelectFlex Orthotics that we will refund 100% of your purchase during the first 30 days if you are not completely satisfied with either fit or comfort. Please see our Return Policy for all of the details.

WHEN WILL I RECEIVE MY SELECTFLEX ORTHOTICS?

Generally, orders placed on our website will be filled the same day. You will typically receive your order within 5 business days of shipment.

HOW LONG BEFORE I FEEL RESULTS FROM WEARING SELECTFLEX ORTHOTICS?

You should feel a difference immediately, but it may take a week or so to fully adapt to your new SelectFlex Orthotics and get the full benefits of this technology.

WHAT SHOULD I DO IF SELECTFLEX ORTHOTICS FEEL LIKE THEY ARE PROVIDING MORE SUPPORT THAN MY FEET NEED?

Simply decrease the selected support level until you find the most comfortable support setting.

HOW WILL I KNOW WHEN I NEED TO ADJUST MY SELECTFLEX ORTHOTICS?

It‘s really up to you. If you are feeling too much support in your arches, simply select a lower support level. If not enough, increase support level.

CAN I HAVE DIFFERENT SETTINGS FOR EACH FOOT?

Yes. This is another unique advantage of SelectFlex orthotics. Some people will have different arch conditions on their feet, requiring different levels of arch support. With SelectFlex you can experiment on both feet to determine which settings are best for your unique requirements.
