The technical-aesthetic qualities of this high quality product are enhanced by the innovative ProComf® Technology, a system that was developed and patented by Sergio Grasso to ensure maximum comfort for the rider.

The system is based on the integration and interaction of three elements:

• The non-slip outer sole produced exclusively for Sergio Grasso by Vibram®

• The natural leather midsole with high tensile steel shank

• The breathable, antibacterial, latex foam insole with activated carbons and a high density, gel shock absorber.
