Saucony - ProGrid Guide 7 Trainers - Grey - Size UK 12

While they offer good protection and comfort for daily training, they may not provide the advanced features or the specific type of cushioning that marathon runners typically seek in modern performance shoes. They are best suited for shorter to medium distance runs or as a comfortable trainer.

As a retro re-release, the sizing might follow older standards. It's recommended to check the size chart and potentially size up or down based on reviews if you are accustomed to modern Saucony fits.

The ProGrid Guide 7 is designed primarily for road running. While they might handle very light, well-maintained trails, they lack the aggressive tread and specific support features needed for technical off-road terrain.

ProGrid technology was Saucony's cushioning and shock absorption system from the 2000s. It aimed to provide a smooth transition from heel to toe and reduce impact forces during the running stride.

These trainers are built on a foundation of protection and comfort, reflecting the durable construction standards of their original release. With proper care, they should offer reliable performance for their intended use.

The 'Guide' series typically implies some level of stability or support for runners who overpronate. However, the exact level of support may differ from modern stability shoes. Consult product reviews or a running specialist for specific pronation needs.

Ensure the correct size is being worn. Break in the shoes gradually with shorter wears before longer runs. Check lacing for tightness and pressure points.

The cushioning may naturally wear down with extensive use. Consider replacing the shoes after 300-500 miles, or when cushioning feels significantly diminished. Regularly check the midsole for signs of wear.

This can sometimes occur with new, darker colored shoes, especially when wet. This is typically minimal and should reduce with subsequent wears. Ensure shoes are fully dry before wearing.
