If you've been ordering custom orthotics for any length of time, crush boxes have probably just been part of the routine. A patient steps in, you capture the impression, pack it up, ship it off, and wait. It works, and for decades, it was simply the way things were done.
But the orthotic industry has changed. Digital scanning technology has matured to the point where it isn't just a high-tech alternative, it's a more accurate, efficient, and cost-effective method for capturing the data needed to fabricate truly custom orthotics. If you've been wondering whether it's worth making the switch, here's a side-by-side look at how these two methods compare.
What is a Crush Box & How Does It Work?
A crush box (also called a foam box impression or foam casting box) is exactly what it sounds like: a box filled with dense foam that captures the shape of a patient's foot when they step into it. The resulting impression is a physical mold that gets shipped to the orthotic lab, where technicians use it as the basis for fabricating a custom device.
It's a tactile, straightforward method that has served the profession well, but it also comes with inherent limitations that have become harder to ignore as better technology has become widely available.
What is 3D Foot Scanning & How Does It Work?
Three-dimensional (3D) foot scanning uses a combination of structured light, depth sensors, or photogrammetry to capture the precise 3D geometry of a patient's foot in a matter of seconds. The resulting digital file is a highly accurate representation of the foot's contours, and arch structure.
With a solution like the SureFit Scanner App—powered by Taika3D's AI and machine vision technology—that scan can be captured directly from an Apple iPhone or iPad and transmitted instantly to the lab through a digital ordering platform. No shipping, no waiting.

How the Two Methods Compare
Turnaround Time
With a foam impression, the clock doesn't start until the package arrives at the lab. That means you're factoring in packing time, carrier pickup schedules, transit time, and any delays along the way. For patients who need their orthotics quickly, this lag can be a real frustration.
Digital scans transmit instantly. The moment you complete the scan and submit the order through the SureFit platform, the lab has everything it needs to begin fabrication. That translates to meaningfully shorter turnaround times and happier patients.
Cost
Crush boxes aren't expensive on a per-unit basis, but the costs add up when you factor in the boxes themselves, shipping materials, and the staff time involved in packing and tracking each order. Multiply that across every orthotic order your practice places in a year, and it's a line-item worth paying attention to.
3D scanning eliminates those variable costs. The SureFit Scanner App is free to download from the Apple App Store and runs on Apple devices many practices already own. Once you're set up, there's no per-scan cost and no ongoing supply expense to manage.
Storage & Space
Crush boxes require physical inventory. You need to keep them on hand, store them somewhere accessible, and reorder when you run low. In a busy practice where every square foot of storage space matters, that's a real consideration.
Digital scanning requires far less physical inventory. Your iPhone or iPad is your scanning device, and your orders live in the cloud.
Patient Experience
Stepping into a foam box is a functional but unremarkable clinical experience. It gets the job done, but it doesn't signal much about the sophistication of your practice.
Scanning, on the other hand, tends to impress patients. Watching a 3D model of their foot appear on a screen in real time makes the process feel precise, modern, and thoughtful, reinforcing confidence in the custom device they're about to receive.
HIPAA Compliance & Data Security
Paper-based workflows and physical impressions don't raise HIPAA concerns in the traditional sense, but the ordering process that surrounds them can introduce documentation and data handling risks. Digital platforms built for clinical use, like the SureFit Scanner App, are designed with end-to-end HIPAA compliance.
So Why Are Some Practices Still Using Crush Boxes?
Habit, familiarity, and the perceived effort of switching are the most common reasons. If your current workflow is functional, it can feel like a risk to change it, even when a better option is available.
The good news is that the barrier to switching is lower than most practices expect. With the SureFit Scanner App, there's no expensive hardware to purchase, no lengthy implementation process, and no steep learning curve. Setup involves downloading a free app and completing a brief activation training call with the SureFit team. Most practices are up and running quickly.
The Bottom Line
Crush boxes were the right tool for a long time. But 3D scanning technology has reached the point where it outperforms foam casting on the dimensions that matter most: speed, cost, patient experience, and workflow efficiency.
For practices that are serious about delivering the best possible orthotic outcomes, digital scanning isn't just a nice upgrade—it’s the smarter standard.
