From watching my FiL wear them I’ve deduced that they are lethal in most weather conditions. I’ve watched him fall and slip in them on numerous occasions. So for comedy value 10/10.
I’ll never wear them as I’m blessed with the feet of a Hobbit and nip outside barefoot if doing the bins, chasing the dog about etc. For prolonged periods I have a pair of Sanuk sandals as I still have a slither of self respect left.
