Leg prosthetic liner SoftskinAir®

transtibialtransfemoralsilicone

Overview
SoftskinAir® is the world’s first breathable silicone prosthetic liner. Micro‑pores in the silicone structure enable moisture and air transfer to the outside, reducing damp sensation during extended wear and improving day‑to‑day comfort and system fit. Developed for O&P laboratories and specialist retailers as a practical daily solution.

Key features

• Patented breathable micropore structure for targeted moisture transfer and improved comfort
• Innovative functional knit to limit longitudinal stretch without an internal matrix
• Integrated stainless steel pin receptacle for high load capacity and durable connection
• Designed for stable guidance and a secure fit during movement

Available variants
For the lower leg (available with or without distal connector)

• SoftskinAir® S30 – Shore hardness 30
• SoftskinAir® S40 – Shore hardness 40
• SoftskinAir® S50 – Shore hardness 50
• SoftskinAir® Sport – Shore hardness 40
• SoftskinAir® 2L – Shore hardness 30/50 (2-layer)

For the upper leg (with distal connection)

• SoftskinAir® TF – Shore hardness 40
• SoftskinAir® TF – Shore hardness 30/40 (variant)

Technical advantages and features (details)
Micropores in the silicone provide targeted moisture transfer to keep the prosthetic interface drier during prolonged use. The functional knit distributes forces evenly and reduces longitudinal stretch, enabling stable suspension and guidance without an internal matrix. The stainless steel pin receptacle delivers a reliable mechanical connection under high loads. Precise dimensions facilitate accurate fitting to individual limb geometries.
