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. **

Pricing is determined based on supply and demand through the interaction of buyers and sellers in the market. When the demand for a product or service increases and the supply remains constant, the price tends to rise as buyers are willing to pay more to secure the limited supply. Conversely, when the supply of a product or service increases and the demand remains constant, the price tends to decrease as sellers compete to attract buyers. Ultimately, the equilibrium price is reached where the quantity demanded equals the quantity supplied, and this is where the market price is determined. **
