About Us

Silicon Dynamic Orthotic (SDO) has been treating walking and running injuries for the past 15 years with our custom made orthotic inserts. Tim Hornak is a licensed physical therapist and owns two orthopedic private practices in Los Gatos and San Jose, California. Being a long distance runner and triathlete for many years Tim knows not only the pain involved of having a running injury but clinically and professionally knows the bio mechanics and mechanisms causing these injuries. It was this background that Tim was able to design the most unique and effective custom made orthotic inserts available today.

Over the years Tim has worked with thousands of recreational runners and walkers as well as many university track teams and Olympic runners from and United States and other countries. SDO Orthotics adhere to one primary goal: keep your patients running and walking pain free.
