Because there is a sticky substance when the mud and your flat shoes make contact. And also boots have a little gap at the top which is why they don't stick like flat shoes!
We slip on a muddy road because mud reduces the friction between our shoes and the surface. When the ground is wet and slippery, the mud forms a thin layer of water on top, making it difficult for our footwear to grip. As a result, our feet can lose traction, causing us to slide or fall. Additionally, the unevenness of the muddy terrain can further contribute to instability while walking.
Mud
lack of friction?
PLACE. example: The car rolled down the muddy road. "down the muddy road" - adverb of place
Driving a bike on a muddy road can be challenging because the wheels can lose traction, causing the bike to slip and slide. The soft surface of the road can also make it difficult to maintain balance and control of the bike. Additionally, mud can clog the bike's gears and brakes, leading to further difficulty in maneuvering.
As compared to walking on unpaved dirt, walking on rigid pavement is easier, and less dirt sticks to your shoes, especially when it has been raining and the dirt road gets muddy.
there are some strollers with almost "off-road" wheels that perform decently in muddy conditions.
It really depends on how muddy it is. If its just a bit muddy, the stock tires will likely be fine. However, if it is really muddy you will need some tires designed for off road mud driving.
It is difficult to walk on a slippery road because the friction between your shoes and the road is compromised. When you stand, its not so much an issue, as most or all of the force vector from your body is pointing down. When you walk, however, there is a horizontal component of the force vector, which is what is accelerating you in a horizontal direction. Since the road is slippery, the coefficient of friction between your shoes and the road is less, causing the tendency to slip or fall.
Gypsy Flat Road was created in 2001.
Walking on a slippery road is difficult because there is reduced friction between your shoes and the surface, making it challenging to gain traction and maintain your balance. This can cause you to slip and fall, increasing the risk of injury. Your muscles have to work harder to stabilize your body, making walking on a slippery road more strenuous.
