"New Boot Goofin'"

Yes, I would recommend this product.

I bought these boots 4 days before climbing Mt. Hood after trying on a pair at a friend's house. What was I thinking!?! Well, let me tell you... I was thinking that I didn't want my shins bleeding like when I climbed Mt. Rainier in a pair of rented plastic mountaineering boots. The only breaking in I did was wearing them while I cooked and ate a frozen pizza in my tiny house. Oh ya, I also paced outside on the sidewalk for about 5 minutes while on the phone. These boots, considering how lightweight they are, proved to have the perfect amount of flexibility while maintaining a certain rigidness backing each step on the mountain with Sir Edmund Hillary like confidence. I did experience a wee bit of heel slippage but did not end up with any blisters at the end of the climb. Would I recommend these to a friend? Yes. Would I recommend these to my mom? Absolutely. Get these boots and quit worrying about it.

"Great Boots!"

Yes, I would recommend this product.

I bought these for a couple of technical climbs I did that summer in the North Cascades and was very impressed with the boots. Virtually no break in period and then two 3 day trips and not a blister. Highly recommend!

"Bridges the gap between hike/approach and climb!"

Yes, I would recommend this product.

Im a big fan of equipment that allows alot for flexibility in weather ,terrain, and even just changing up your plans. For these reasons these boots are perfect for me. Mostly day trips, middle altitudes,nothing lower than single digits most of the time.....but all the while knowing if I get the chance to take them into gnarlier terrain or weather they will really do well and be super comfortable and functional as well. As many have stated....they do run a tiny bit aim a little higher than usual when you are settling on a size.
