The Michel Vaillant Egg Bar shoe where the rear ground bearing surface surface is behind the heels and frog. Front shape. Made from hi-tech aluminium alloy. PRINCIPLE AND INTERACTION WITH THE GROUND: Bevelled outer rim at rear to reduce the rear lever arm and limit the ‘snowshoe’ effect during the foot-landing phase. Large bevel on the outer rim to increase rolling at toe, side walls and quarters. Wide rear ground bearing surface cross piece to increase support and limit heel penetration on compacted and penetrable grounds. Pierced cross piece with offset holes to facilitate shoe transformation when a narrower or wider shape is required. BIOMECHANICAL AND KINETHERAPEUTIC EFFECTS: Reduces stresses during propulsion in straight lines and turns. Reduces stresses on the distal sesamoid bone and on the deep digital flexor tendon. Reduces general stress on the podotrochlear apparatus. INDICATIONS: Grade 2 navicular syndrome. Lesions of the deep digital flexor tendon or its accessory ligament (distal check ligament). Non-tempered alloy can be used for risk-free hot shoeing up to 450°C. 10 mm thickness, with 3 clips that can be ground off for customization. Made in France. Sold per pair (2 shoes).
