Food for thought
I’m in podiatry school and I’m currently in rotations with doctors dealing with custom orthotics almost daily. They can be a powerful tool to help you’re overall foot health. The price sheep feet charges is actually very reasonable for custom orthotics. It seems like a well made orthotic and could benefit most anyone who tries them, even an OTC insert could do wonders as they generally support the foot much better than anything the boot/shoe companies put in their product.
That said custom orthotics are historically done with a Podiatrist or orthopedist first completing a biomechanical exam of that particular person. There’s seriously dozens of different modifications that can be done to an orthotics prescription which to me is what makes the orthotics truly custom.its a game changer for some people who need those modifications. Another benefit of doing orthotics through a doctor or clinician is some insurances will cover or partially cover your orthotics through them. For most, these sheep feet semi custom route will work great but if you have issues or pain it might be worth the effort or extra money to visit the doc first and get something that could help even more.
