What’s the Difference Between the Surestep SMO and SMO3D?
The original Surestep SMO has been a clinically trusted solution for children with hypotonia for more than 25 years, built on a compression-based design that stabilizes the foot and ankle while supporting natural development. The new SMO3D expands on that foundation, reimagined through modern 3D printing technology. Both share the same clinical approach and are designed to deliver the outcomes clinicians rely on. So, which one is right for your patient?
Key Differences at a Glance

|---|---|---|
| Fabrication Method | Traditional thermoplastic | 3D printed |
| Weight Limit | Up to 90 lbs. (model-dependent) | < 50 lbs. |
| Fabrication Time | 4-8 business days + shipping | 5 business days + shipping |
| Rush Ordering | Available | Not available |
| Designs / Modifications | Multiple models & modifications | None currently—expanded design choices coming soon! |
| Adjustability | Highly adjustable | Minor adjustments only |
| Heel Post | Thermoplastic heel post | Narrower heel post allows for easier shoe fit |
| Breathability | No perforations | Perforated throughout for added comfort |
| Malleoli Comfort | Cut-outs available in the Big Shot models | Auxetic structures contour around the malleoi |
| Cosmesis | Fun transfer patterns available | 5 vibrant solid colors |
| Footplate Trim Lines | Standard trim lines or modifications available | Standard trim lines only |
| Straps, Pads | Same | Same |
The thermoplastic Surestep SMO under our Dynamic Stability line includes several modifications, giving clinicians flexibility for a wide range of patient needs:
- Open Heel: Features the Surestep SMO with an open heel modification. This design facilitates posterior weight shifts to encourage improvements in squatting, development of a heel-toe gait, and increased sensory input.
- Big Shot: The perfect SMO solution for older children or children over 80 lbs. who still need stability.
- Toe Walking: SMO modification designed for patients with low tone who toe walk due to sensory or stability concerns.
- Reverse Trim Lines: Foot trim lines to address metatarsus adductus or excessive supination
- Clubfoot Modifications: Abducts the forefoot 5-7 degrees and utilizes reverse trim lines
We also introduced the Max Control SMO under our Alignment Control line that offers more rigid control of the foot and ankle, featuring a full footplate to improve foot and ankle alignment and stability for confident movement.
Having both a thermoplastic and a 3D-printed option means you can match the device to the patient, not the other way around. The SMO3D tends to be a strong fit for lighter patients (≤50 lbs) where shoe fit, breathability, or wear compliance is a priority. The narrower heel post and low-profile silhouette make it easier to fit into most footwear, and the perforated design helps with heat regulation. If your patient needs more significant customization, weighs more than 50 lbs, or you need a rush order, the thermoplastic Surestep SMO may be the better option. As always, the right choice depends on your clinical judgment and the individual needs of your patient. These guidelines are simply a starting point.
Frequently Asked Questions (FAQs)
Q: What is the turnaround time for SMO3D?
Five days plus shipping.
Q: Is rush fabrication available for SMO3D?
No, if you need a rush order, we recommend utilizing the standard Surestep SMO.
Q: How can I submit my order?
Orders can be submitted through our online ordering portal or by emailing an order form to [email protected]. Our team can fabricate based on measurements, scan, or cast.
Q: Is it easy to heat adjust or change the strap/chafe location?
The SMO3D Modification Guide provides more information on available modifications. If you need to change the chafe location, contact customer service at 877.462.0711.
Q: Can the perforated area be trimmed back?
Please do not trim the perforated area, as it will compromise the integrity of the device.
Q: How much does SMO3D cost?
For more information on pricing, please contact our customer service team.
Q: What are auxetic structures?
Auxetic material structures widen when stretched and narrow when compressed. In the SMO3D, these structures allow the SMO to flex and expand around the malleoli for added comfort and freedom of movement.
Q: What kind of customizations are available?
Currently, the SMO3D is a more standardized device due to the manufacturing process. If customization is required beyond what we offer in the ordering portal, we recommend exploring thermoplastic options like the Surestep SMO.
