Adidas speedex 23 size 10

Start with your running goals and foot type to guide the selection. If you log long miles on roads, prioritize cushioning and a supportive midsole; for speed workouts, look for lighter uppers and a responsive foam. Adidas offers a range of options in synthetic and textile uppers. Try different fits and consider brand recommendations for your arch, gait, and preferred surface to land on consistently.

Synthetic uppers tend to be durable and weather-resistant, offering structured support for steady miles. Textile uppers are lighter and breathable, often remaining comfortable in warmer conditions. Your choice depends on climate, sensitivity to heat, and how much ventilation you want during runs. Both materials can deliver solid performance with the right cushioning and outsole design.

For long distances, select shoes with enhanced cushioning to absorb impact and reduce fatigue. For speed work or racing, a lighter, more responsive design helps you accelerate quickly. Balance cushioning with stability to prevent fatigue, and ensure the fit remains secure during changes in pace. Adidas offers options across these needs to match your training plan.

Outsole tread affects grip, durability, and stability on road surfaces. A shallow, smooth tread reduces rolling resistance for faster sessions, while deeper lugs excel on mixed terrains. For regular pavement running, prioritize a durable rubber compound with good wear resistance and a tread pattern designed for consistent ground contact.

Measure both feet and try on shoes at the end of the day when feet are slightly enlarged. Ensure about a thumb width of space in the toe box and a snug heel hold to prevent slipping. If between sizes, opt for the larger size for comfort on longer runs. Consider wide or narrow variants if your foot shape requires it, and refit after a break-in period.

Keep shoes dry after runs and clean them with a soft brush or cloth to remove dirt. Let them air-dry away from direct heat to preserve midsole and outsole integrity. Rotate pairs if possible to reduce wear on a single pair, and replace shoes once cushioning or stability noticeably degrades. Regular inspection of the outsole ensures continued traction on roads.
