I am due to go to Poland next week. I checked the weather and it's -11.
I am somewhat prepared with a wool jumper and socks and hat.
I am anxious about shoes. I have runners but I think they might not be suitable for snow/ice.
Should I get a hiking boot/shoe for the trip? Something with a good grip at the end of the shoes? I won't be able to bring spare shoes due to baggage allowance. Would shoes be hard to break into now? I have wool socks.
