Soles are VERY Slippery!
I could tell the moment I put them on that the soles seemed stiff and unyielding, so I was very careful as I started down my hardwood stairs.
Even so, my feet shot out from under me and I fell down the entire flight. I was heading to work, so I could not stop to examine my injuries.
I ended up sore and bruise, but no lasting injuries.
On the way to the bus stop I scuffed them like mad against the rough pavement to try to maks eom traction. They are a little better now, but still much more prone to slips than any other shoe/boot I own.
