Built for speed, the Adizero Prime X3 STRUNG is a high-performance race day shoe that puts innovation first. The blue STRUNG upper keeps a secure foothold, while encouraging breathability and flexibility where you need it most. For maximum comfort, a three-layer Ligthstrike midsole is combined with carbon fibre-injected ENERGYRODS 2.0.0 and a top carbon plate to deliver lightweight propulsion so you can get the most from your run. The high milage super trainer is back, tuned, tested and constructed for a lighter, faster feel than before, still containing stacks and stacks of their pinnacle technology to help give you PBs and smooth training runs. With a new dual stiffening construction, the adidas Adizero Prime X3 Strung features both a carbon plate and Energyrods 2.0 to give a snappy feeling and an enhanced approach to energy propulsion. Three layers of Lightstrike Pro sit around the stiffening agents, with a massive 50mm stack height providing cushioning, speed and lightness in abundance. The Strung upper, built up layer by layer for the perfect combination of lightness, breathability and hold has been improved, and an allnew outsole uses the lightweight traction of Lighttraxion with continental rubber at toe off for complete confidence in any weather.
