Intercity traffic is considered long-distance.

Stopper socks and jump socks are not the same thing. Stopper socks typically have grips on the bottom to prevent slipping, making them ideal for activities like yoga or pilates.

While both types of socks serve a similar purpose of providing traction and safety during physical activities, they are designed for different types of exercises. **
