How to walk on slush?

I found this cute bench beside the Church of Saint Peter (a.k.a. St Petri, Swedish: Sankt Petri Kyrka) in Malmö, Sweden. I guess I should have visited Malmö in summer and sat on the bench for a while. It looked so cosy if it was in summer. I was there in January and the square next to the church was slush and there were also piles of snow. Come to think of it, recently I talked with my English acquaintance how to walk on slush. It's said you should take small steps and don't lift your foot completely off the ground. It sounds like a penguin's walking method, but the point is penguins don't have knees. That's the difference between us.
