The Vasyli Prior incorporates a subtle 4mm heel raise – perfect for those tight posterior muscles and associated conditions such as Achilles Tendinitis.

The rear foot post of 3° + the 4mm raise forms a smart medial wedge giving control without the "bulk".

Low profile medial arch contour ensures comfort while the high density heat moldable shell provides further customization, enhancing fit and performance.

The intrinsic fore foot contours balance the unique fore foot loads experienced with studs / cleats and further enhances 1st ray plantarflexion, facilitating Hallux dorsiflexion.

In turn this assists in instigating the Windlass mechanism - promoting "high Gear" propulsion, stabilizing the fore foot, locking the mid foot for maximum power transfer during heel up and toe off.
