adidas adizero Prime X 3 Strung - Blue - UK 5.5

This shoe is ideally suited for long training runs, tempo runs, and interval workouts where you want maximum cushioning and propulsive speed. It's also excellent for personal best attempts in unofficial races or time trials.

No, the adidas adizero Prime X 3 Strung has a 50mm stack height, which exceeds the 40mm limit set by World Athletics for official competitive races. They are perfect for training and unofficial speed attempts, but not for sanctioned competitions.

The Strung upper is engineered layer by layer, precisely placing threads for targeted support, breathability, and flexibility. This results in a lighter, more adaptive, and highly breathable fit compared to traditional woven mesh constructions.

Lightstrike Pro is adidas's superlight, highly resilient foam that provides maximum cushioning and energy return. In the Prime X 3 Strung, three layers of this foam contribute to its massive 50mm stack height, offering exceptional comfort and speed.

The adidas adizero Prime X 3 Strung has a heel offset (drop) of 7mm (50mm heel / 43mm forefoot).

The adidas adizero Prime X 3 Strung weighs approximately 275g (for a UK 5.5). Weight may vary slightly by size.

The outsole combines Lighttraxion technology for lightweight grip across the shoe with Continental rubber strategically placed at the toe-off area. Continental rubber is known for its superior grip in both wet and dry conditions, providing confidence during propulsion.

The Strung upper is designed for a secure fit. Ensure you are wearing appropriate running socks that are not too thick. Re-tie your laces, paying attention to pressure points. If discomfort persists, check your sizing, as an incorrect size can lead to issues.

The Prime X 3 Strung has a very high stack height (50mm), which can inherently reduce stability for some runners, particularly those who overpronate or have weaker ankles. Focus on strengthening your ankle and foot muscles. For sharp turns, reduce speed. These shoes are optimized for straight-line running.

Ensure your running form utilizes the midfoot to forefoot strike to fully engage the carbon plate and Energyrods 2.0. The benefits are most apparent at faster paces. If still not feeling it, ensure the shoes are adequately broken in (usually a few runs).

While the Lighttraxion outsole with Continental rubber offers good grip, no shoe is entirely slip-proof in extreme wet or icy conditions. Ensure the outsole is clean of debris. Adjust your stride and speed for wet surfaces, as even the best traction has limits.

Running shoe lifespan varies based on mileage, running style, and surface. To maximize durability, rotate your shoes, follow proper care instructions (cleaning and drying), and consider if your gait might be causing excessive wear in specific areas. The Prime X 3 Strung is a performance trainer, and while durable, it's not designed for extreme off-road use.
