The Hard Reality of Artificial Turf
Artificial turf has changed the game, but it comes with a cost. Unlike natural grass, turf surfaces create significantly more friction. The combination of synthetic blades and rubber infill is highly abrasive, leading to the common and painful problem of "turf burn" during slides.
For a goalkeeper, repeated knee contact during training drills and diving saves on this surface can cause discomfort and skin abrasions, impacting performance and confidence. This is why goalkeeper knee protection is becoming increasingly important.
