"Ever since I started using the Crosskix Orthotics in my golf shoes, not only has my prior knee pain disappeared, but I have been able to perform at a higher level than before. I am no longer worried about twisting a certain way to irritate my knee. I have a high arch foot that no orthotic I've tried before has been able to support. The sturdy base of the Crosskix orthotic also allows me to stay planted and step with confidence. I am so happy to have implemented my Crosskix Custom Orthotics into my lifestyle."

How Do Orthotics Work?

Orthotic shoe inserts realign the foot to neutral and redistribute pressure so every step feels natural. The right insoles for plantar fasciitis cradle your arch, act as effective shoe inserts for heel pain, and stabilize the ankle-knee-hip chain, whether you’re training or on your feet all day.

What the right inserts can help with

  • Heel pain: Our plantar-fascia–supporting design offloads the band to tame that sharp first-step sting, precisely what you want from shoe inserts for heel pain.
  • Stability: As shoe inserts for pronation and shoe inserts for overpronation, they guide excess inward roll back toward neutral; as shoe inserts for supination, they add lateral structure so your ankles, knees, and hips stay aligned.
  • Impact & forefoot pressure: Shock-absorbing cushioning and a metatarsal pad spread load, think shoe inserts for shin splints and arch support inserts for shin splints. Our orthotic insoles for running provide extra stability and impact protection for active feet, reducing strain during long workouts. Meanwhile, our metatarsalgia insoles and insoles for Morton’s neuroma deliver targeted relief and arch support for Morton’s neuroma. We also craft orthotics for plantar fibroma and orthotics for plantar fibromatosis.
  • All-day comfort: Built like the best orthotics for work boots with cloud-soft cushioning, they keep you supported on hard floors for hours, the reason many call them the best insoles for standing all day.

Why Are Orthotics a Great Choice?

Your feet are the base for your whole body. The right custom orthotic insoles support your arches, align ankles, knees, hips, and spine, and improve balance, posture, and stride while reducing stress on muscles and joints. Orthotics are a simple, drug-free, surgery-free way to get relief. Slip them into your shoes and feel immediate support and comfort especially for common issues like heel pain, flat feet, high arches, pronation, overpronation, and supination.

FAQ

Frequently Asked Questions

Unlike the flimsy or gushy inserts from the store or pharmacy, custom-made orthotics that are 3D fitted to your feet are strong, add stability to your step, and help correct your gait and posture issues while being soft and comfortable. There is also no need to cut them to fit your shoe, as custom-made orthotics are sized exactly to your foot.

Our custom-made orthotics are equal or better quality than the custom-made orthotics available from a podiatrist or doctor's office. In fact, many clinics trust us to design & manufacture the custom-made orthotics they give to their patients. However, we allow you to order your own orthotics from the comfort of your home at a fraction of the cost and offer free assessments, free custom-fitting, and free shipping.

Orthotics that are properly fitted and custom-made can help treat, alleviate, or prevent: Heel/foot pain and/or swelling, flat feet, high arch, plantar fasciitis, poor balance and/or stability, turf toe, shin splints, ankle pain, hip pain, back pain, low mobility, pronation, supination, knee pain, lower limb pain, obesity, neck pain, back pain, spinal pain, and many other musculoskeletal conditions.

Orthotics can be customized with a wide variety of design elements and material combinations, however, they should be fabricated based on the overall health status of each individual. We design custom-made orthotics based on your: 3D foot structure/depth, body weight, age, lifestyle (type of work, physical activity & intensity), preferred footwear & more.

As soon as we receive your digital scan from our app, your custom order is placed in queue and we begin to model, design, and handmake your orthotics. With no need to wait for physical foot impressions to ship, we can deliver custom handmade orthotics to your door in weeks instead of months!

You will feel the added support & stability of your orthotics immediately. Some pains and/or conditions can be relieved after a few days/weeks of orthotic use.

Our orthotics are interchangeable, however, they should only be transferred between the same type of shoe. Orthotics designed for heavy boots or running shoes will not function properly inside of a dress shoe.

Since each pair of our orthotics are specially formulated for a certain scenario or shoe type, we recommend ordering a pair of orthotics for each pair of shoes that you wear. For example, one pair for exercising and one pair for work or casual use. If you own a lot of shoes and are having trouble deciding, start by ordering orthotics for the shoes you wear the most.

This depends on frequency of use. Our orthotics are made using materials that are high quality, ultra durable, and long lasting. However, since orthotics are corrective devices, we recommend getting new pairs every 12-36 months to ensure that they are up-to-date with your feet.

The Crosskix app is currently supported on Apple iPhone generations X. 11. 12. 13, 14, & 15. Click here to download from the app store.

If your screen shows up black during the scan, you need to allow the app to access the camera. Go to your phone's settings, scroll down and press on the Fits app, and then toggle camera access ON. Another option is to reinstall the app but this time, when asked, make sure to allow camera access.

If your camera is working but your foot is not being captured, make sure you are in a brightly lit area, and make sure you are holding your foot flat & level with the ground. If you are sitting down, try again while standing up.
