Neither have I had troubles with blisters, although I feel my feet “slipping” a bit inside the inner boot when traversing rough inclines or really uneven ground. Personally I would rather have a bit of slippage than having a tight fit with less flexibility. Bringing the laces behind your ankle, tightening and then bringing them to the front to tie them off is key to keeping the slippage to a minimum and increasing general comfort while walking.

If I should mention one thing that doesn’t seem to be 100% in order it is the velcro closing mechanism on the inner boots. These seem to be prone to breaking down after using them for a while. Luckily it isn’t really a problem since you won’t be able to tell the difference if they are closed off or open during a hike, and the inner boot is 100% freestanding and replaceable.

I wore them on my 3 day (60ish km) hike from Oslo to Hadeland in late October. Conditions were soaking wet and muddy the entire way, with the trails often being small rivers, but the mucks kept me dry.

They performed a similar role when grouse hunting in the mountains in November.

A big plus with the removable inner sole, outside of easily being able to dry them, is that you can remove them and put them in your sleeping bag at night to avoid having to put on ice cold shoes in the morning. This is something people camping outside in cold conditions should be able to relate to.

I have also used mine mountain hiking in semi-snow and whilst ice fishing with the woolen inner shoe. I was a bit skeptical of the built-in gaiter, but these have pleasantly surprised me with being comfortable to wear and keeping snow and dirt out.

For static use in winter (i.e whilst ice fishing), I would recommend buying a thicker insulating sole in addition to the woolen inner sole.

Could not recommend these enough.
