The Total Surface Bearing (TSB) socket is one of the most advanced and widely used socket designs for below-knee (BK) amputees. Unlike traditional designs that focus pressure on specific “tolerant” areas, the TSB socket distributes weight evenly across the entire surface of the residual limb. This design promotes comfort, limb health, and a secure fit throughout the day.
Key Features of the Total Surface Bearing (TSB) BK Socket
Even Pressure Distribution
Reduces high-pressure zones, promoting better blood flow, skin integrity, and overall comfort.
Gel Liner Interface
Works with silicone, urethane, or TPE liners to cushion the limb and reduce shear forces.
Multiple Suspension Options
Compatible with:
-
Pin-lock systems
-
Seal-in liners
-
Suction suspension
-
Elevated vacuum systems
Each system enhances socket stability and minimizes movement (“pistoning”).
Custom Molded Fit
Every TSB socket is fabricated from a cast or digital scan of the patient’s limb to ensure intimate contact and an anatomical fit.
Improved Proprioception
A close-fitting socket improves limb awareness and balance, contributing to better gait and control.

All-day Comfort: Reduces pressure points and hotspots
