Why walking on pebbles with bare feet does not hurt when you enter the sea?

Walking on pebbles with bare feet may not hurt when you enter the sea because the water provides a cushioning effect, reducing the direct pressure on your feet. Additionally, the buoyancy of the water can alleviate some of the weight and impact, making the pebbles feel less harsh. The cool temperature of the water may also distract from any discomfort, allowing you to focus more on the refreshing experience.
