This really really depends on what you will be doing in the Yukon and where you will be going. If it is maintained trails you may do absolutely fine in trail shoes with good socks. If you are up high or in rougher country you may do better in boots.

It also depends on your experience level - do you currently have shoes/boots you are comfortable in?

So - where are you heading in the yukon and what will you be doing?

Any fool can be uncomfortable...
