6. Assess the angle of the toes: Authentic Vans typically exhibit a slight upward bend at the toes, allowing them to face upward. If the bottom of the shoes appears flat, it may indicate counterfeit products. Additionally, test the flexibility of the toes by pressing on both the heel and toe simultaneously; authentic Vans should bend easily, allowing the back and front of the shoe to touch. Stiffness may suggest counterfeit items.
