What happens when you step on a karate Matt with shoes?

Stepping on a karate mat with shoes can transfer dirt and grime from the soles onto the mat, compromising its cleanliness and potentially affecting the safety and grip for practitioners. Karate mats are designed for bare feet to ensure optimal traction and reduce the risk of injury. Additionally, wearing shoes might violate the dojo's etiquette or rules, as many Martial Arts disciplines emphasize hygiene and respect for the training environment.
