Saucony Triumph 23 GTX Trainers - Black - Size UK 7

The XT-900 outsole provides decent traction, making them suitable for light trails and gravel paths. However, for technical or very muddy trails, a dedicated trail running shoe with more aggressive lugs would be recommended.

Refer to Saucony's official size chart available on their website, which typically compares foot measurements to UK, EU, and US sizing. Ensure you measure your foot length accurately, preferably at the end of the day when feet are slightly swollen.

Yes, the comfortable cushioning and supportive design make them suitable for walking and general daily wear. However, their primary design and optimal performance are for running.

The key difference is the GORE-TEX Invisible Fit technology in the GTX version, which makes the shoe waterproof and more suitable for wet conditions. The non-GTX version will generally be more breathable.

Running shoe midsoles typically lose their cushioning and responsiveness after 300-500 miles. Factors like your weight, running style, and the surfaces you run on can affect this lifespan. Inspect the shoes regularly for signs of wear.

GORE-TEX Invisible Fit is designed for breathability alongside waterproofing. While generally effective, in extremely hot and humid conditions, any waterproof shoe might feel warmer than a non-waterproof mesh shoe.

Ensure socks are also moisture-wicking. Check for any leaks around the shoe's seams or if the GORE-TEX membrane has been compromised. Ensure the shoe is not submerged in water for extended periods.

The PWRRUN PB midsole may lose some of its responsiveness after significant mileage. Normal wear and tear is expected; consider replacing the shoes after approximately 300-500 miles of use.

While the XT-900 outsole offers good traction, extremely slick surfaces can still pose a challenge. Ensure the outsole is clean from debris. For very challenging conditions, consider a trail-specific shoe.
