What is the required specification for the footwear worn by players, umpires, and markers?

The correct specification for footwear worn by players, umpires, and markers in bowls is flat-soled shoes. This requirement is established primarily for the safety and fairness of the game. Flat soles help provide stability during play and prevent slipping on the green, which is crucial since the playing surface must remain undisturbed to ensure fair conditions.

Footwear choices that include high-heeled shoes or any type of shoe that does not adhere to the flat-soled requirement can create hazards on the playing surface as they may cause players to lose balance or mark the green. Additionally, although sneakers may provide grip, they can come in various forms that may not meet the flat-sole requirement, potentially affecting the accuracy and judgment of play. The focus on flat-soled shoes ensures that all players can compete on equal footing without the risk of unintentionally damaging the green or slipping during their delivery.
