Meindl Winter Boots, Size 10

Meindl Kibo Goretex 300 isulated boot. Perfect winter boot for hiking, hunting or even ice fishing. The sole of the boot has small shards of metal that improve traction on ice. These boots are too small for me. I wear a 10.5 but the website said to size down a half size if haven't worn the boot before. The boot is a size 9 UK and 43 EU, which is a 10 in US sizing. For me they are snug with a light sock but way too tight with a heavy winter sock. If your normal shoes size is a 10 then these will most likely be ok. Below are the links to the Meindl website and the sizing chart. These boots are very high quality and very warm. Only worn outside once. Asking $350.
