Customer Voice

“Piro Flex SMOs fit perfectly and our little friend popped right up and almost started walking right out of the gaits!

Loved the feel and the fit of them and the PT referral that I was working with was very impressed with the design and low-profile fit of them.

Thanks again for making such a great product.”

Caleb Klinge, CPO

“My goal is to pursue adding integrated cushioning into our devices.

Piro® Fusion SMO has absolutely 100% nailed it!

These relief areas are incredible.

Not to mention to seamless transitions in this multi-material design.

This orthosis design is seriously everything I've ever wanted to incorporate into O&P devices.”

Derick Schmidt
Shore Prosthetics & Orthotics

“We've loved the Piro® Flex SMO's. Every time I fit a kiddo with them the measurements have been very precise and an overall great fit.

Parents and therapists are always impressed with the product and comment that it seems more comfortable than other products they've seen in the past.

It also seems to capture the calcaneus and provide a good arch and navicular support to correct pronation, without needing to add extra padding.

Our daughter has been wearing hers for about a month and hasn't complained once about wearing them and they seem to be helping her in every way we expected.

Customer support has also been very helpful and responsive to any questions, feedback or requests I've made. Overall a great product and company.”

Dallen Wheelwright, PT, DPT
Goal Pediatric Orthotics

“The patient and her mother couldn't say enough good things about the SMOs.

Some of the things that they mentioned were:

- They're much more lightweight and breathable
- The patient is able to done them independently
- They fit much better within the shoe
- The low profile allowed her not to go up a shoe size

Thanks for helping develop such a great product!”
