I also had trouble with the Kentreks. I really wanted them to work, but just couldn’t get to a comfortable place. I went with the Crispi Guides and absolutely love them. No problems. Bottom line though, everyone’s feet are different and you just gotta find what works for you.
I really struggled with my Kentreks because the soles are so narrow and tall. It felt like I was expending extra energy, both physically and mentally, trying to balance on rough terrain. I really wanted them to work. Switched to Crispi and love them!
I used the Kuiu 2300 for 5 seasons and packed out many animals including a couple large whole bone in elk quarters. It always seemed indestructible and I loved the design. Zero complaints about it. Would 100% buy it again.
I’m in California and have had nights where my 0 degree was just enough! My experience is that they never really hold up to what they claim and it’s better to go warmer.
