Adapt your field setup to any environment with the Champion Sports Universal Soccer Corner Flag Set, a flexible solution for both indoor and outdoor play. Ideal for gym floors, turf fields, or traditional outdoor surfaces, these flags use a hollow base that can be filled with sand for added stability where ground spikes aren’t an option. The tall, highly visible design keeps boundaries clear during games and drills, while the sturdy poles hold up to repeated use. Easy to set up and reposition, this set offers a practical way to mark corners or training areas without limiting where you play. Each set includes four red corner flags with fillable bases for reliable, versatile performance.
