Runners fasten by using laces or straps to secure their shoes to their feet. The laces are typically tied in a knot to ensure a snug fit, while straps may use a buckle or Velcro to secure the shoe in place. This helps to prevent the shoes from slipping off during running and provides stability and support to the feet. Additionally, some runners may use specialized lacing techniques to customize the fit of their shoes for added comfort and performance. **
