⚠️ Warning to customers considering the Adizero Prime X 2.0 Strung Running Shoe ⚠️ I bought this model and discovered a serious defect in the right sole — a loud clicking sound and pressure point that makes it unusable (suspect a defect with the carbon sole). This only becomes clear once you actually wear the shoe, not when it’s in the box. Even though I shared both photos and a video clearly showing the issue, Adidas Singapore has refused to replace the product, hiding behind their “unused and unworn” return policy. This is unacceptable for a premium running shoe. Customers should be aware: if you buy the Adizero Prime X 2.0 Strung and it turns out defective after first use, Adidas Singapore will not stand behind their product.
