Bend your knees to lower your center of gravity and land slowly with your whole foot.
If you land heel-first as in normal walking and slip, it’s harder to recover your balance, which increases the risk of falling.
If you take large steps and slip, you're more likely to lose balance and find it difficult to recover your posture. By taking small steps, you can more easily regain your balance if you do slip.
Carrying items in your hands makes it harder to maintain balance, increases the chance of a bruise if you trip, and makes it difficult to break your fall if you do fall. This includes not only heavy items but also small items like mobile phones.
It's best to keep both hands free so you can break your fall properly if you do fall.
Even though it's cold outside, keeping your hands in your pockets is extremely dangerous. For warmth and safety, wearing gloves on both hands is essential in Hokkaido winters.
