Re: Nov-Dec in London
it can snow in December. you may land right in the middle of a blizzard even.
snow shoes have thick rubber soles which prevent slipping and also has insulated interior to keep your feet warm and it’s laces are usually above ankle to avoid snow getting in your shows where there is a pile of snow.
i mentioned snow shoes [NOT boots] from slipping point of view…if you have never walked on snow before, you better have one coz a slip N fall can be dangerous.
