Aaron is very professional. I have been using his orthotics for many years hiking in rough terrain. They helped a great deal with some issues I was having with one ankle. I recently purchased a pair for my bike. I highly recommend this business.
Aaron is the absolute best! He is kind, professional, and exceptionally brilliant at what he does! I have suffered from orthopedic problems all my life and I got my first pair of PTI orthotics from Aaron 10 years ago- which have served me so very well, keeping me aligned and out of pain! I just went in to get them refurbished and am so glad Aaron is still in Boulder. I decided to get a second pair made so I don't have to switch them in and out of my favorite shoes. If you need orthotics Aaron is the one who will make you a pair to last and to keep you feeling great! Without orthotics from Aaron I would not be able to hike, run and be active in my life the way I am now! THANK YOU AARON and PTI!
Aaron is a highly skilled engineer and developer of Orthotics. I have suffered with pronation and pain in my hip, leg and foot for over a year. He created and made adjustments to my custom orthotic over the year. Together, we are working to get it right. He takes the time to teach and offer generous support. I am so pleased with his care and attention. He is a 5 Star practitioner!
Just a note to say great job. I've used referrals from UC Health and OTC products without success, but Aaron was fantastic. Initial fit was great, but months later, an adjustment was necessary. No Charge! Good man, good practice - can't recommend him enough.

Hand‑crafted custom foot orthotics are shaped precisely to your unique anatomy, giving you more accurate support and better alignment than mass‑produced inserts. Their tailored design can improve comfort, reduce pain, and enhance overall foot function in a way off‑the‑shelf options simply can’t match.

CNC machining creates custom foot orthotics with exceptional precision because it follows exact digital measurements rather than relying on manual shaping. This automated process reduces human error and produces more consistent, highly accurate results for every pair.

Non weight bearing neutral position casting has been the gold standard since the 1970's and is now being phased out by non weight bearring 3D scanning. Superior intra / inter tester repeatability. Captures intersegmental malalignments within the foot.

Superior shock absorption while disapating ground reaction forces. Enhanced durabily and will not compress like foam cushioning materials. Superior soft tissue supplement.

By incorporating different densities of materials within the structure of the orthotic, these devices can offer specific areas of the foot targeted cushioning and support. Bony protrusions can be accommodated while supporting the other critical areas of the foot. This is not possible without a positive model. Direct molding techniques do not create a positive model of the foot.
X
Long lasting ultra strong designs that hold the angles molded and machined into the orthotics not possible when using direct molding techniques because no foot models are created with those older systems. These materials mold at 350F and higher and cannot be used in direct mold systems.
X
Ultra‑strong, thin carbon‑fiber composites provide superior performance in certain orthotic applications because they deliver exceptional support without adding bulk. This allows for precise biomechanical control while keeping the device lightweight and low volume.
X
Sport‑specific orthotics are beneficial because they’re designed to match the unique movements, forces, and demands of a particular activity, giving athletes more precise support. This targeted design can improve performance, reduce fatigue, and lower the risk of injury by keeping the feet and body aligned during sport‑specific motions.
X
Pathology‑specific custom foot orthotics are beneficial because they’re designed to address the exact mechanical issues caused by a particular condition rather than using a one‑type-fixes‑all approach. This targeted design can reduce symptoms more effectively and support better long‑term function by matching the orthotic to the patient’s specific needs.
