Just moved into a new condo on the 2nd floor. This morning I grabbed my bike and headed downstairs with my wife. I stepped in some water on the steps and since cleats offer about zero traction my foot basically flew away. If I hadn't been carrying my bike I probably could of caught myself but there was no chance of that happening this time so I landed on my back and ass. Let me tell you, stairs to the back don't feel good.
Anyways I have learnt and important lesson: It's a good idea to wait on put your bike shoes on at the bottom of the stairs.
Luckily I had my helmet on because I hit my head as well.
