What is gross stuff that grows on feet?

Gross stuff that can grow on feet includes fungi like athlete's foot, which causes itching and peeling skin. Calluses and corns, which form due to friction and pressure, can also develop on the feet, leading to thickened, hardened skin. Additionally, warts caused by the human papillomavirus (HPV) may appear on the soles or toes. Proper foot hygiene and care can help prevent these issues.
