A  forward-moving company

At De Oro Devices, we build mobility solutions that empower those in need.

NexStride began with a Cal Poly State University, San Luis Obispo project. Challenged to create a tool that would alleviate and prevent freezing of gait in a local veteran, our simple prototype gave him much needed relief. We soon realized the global potential for our product.

Our team at De Oro Devices has spent countless hours researching and refining NexStride so that it is intuitive to use and blends seamlessly into daily life, ensuring optimal impact with minimal intrusion.

Today NexStride has helped countless individuals take back their freedom and their confidence—and we’re just getting started. A single step can be vital and we’re honored to help you take it.
