I.A.S provides state-of-the-art prosthetic socket design and components. Comfort begins with a properly designed socket. We use careful hand-casting techniques and build prostheses that both support weight bearing and relieve pressure regions. We use flexible inner socket liners to allow the limb musculature to expand and contract throughout the gait cycle. In our above-knee prosthetic designs this flexible liner is supported by a lightweight rigid frame, which attaches to the prosthetic knee of choice. Many types of prosthetic suspension systems, including suction fitting and locking pin mechanisms are used. We use all of the advanced technology feet that will enhance the function of each prosthesis.
