Not a great choice

Originally posted at k2snow.com on Jan 26, 2022
Super lightweight I like. Medium stiffness and a BOA system pretty good. However a pull strap is meant for pulling...not tearing off on day 1. poor quality there. The synch strings are already worn to the point and are starting to fray. Pay a little extra and get something better.

Not Good Quality, Not Recommended!

Originally posted at k2snow.com on Dec 8, 2021
I brought this new set of ROSKO Snowboard boots on November 21st from Sporting Life here at Calgary Canada for my 15 years old boy, he used it once on Nov 26th for this year’s season the very first time, only after a couple hours of use, his left-foot boot’s front-right corner rubber piece came-off a big piece where you can see through its inner layer of the boot. We brought it back to the Sporting Life local store and asked for a quality exchange but the store wouldn’t let us to exchange it at all. As K2 is supposed to be a quality brand, we were surprised that it wouldn’t let us to do a quality exchange as it was only used for the very first time. My son is an intermediate snowboarder and he knows how to wear and use the boots properly, he is a K2 fans where he uses the K2 snowboard, K2 bindings and boots, and he is expecting his new boots to last, but this didn’t leave him with the good experience with K2 and the Sporting Life store going forward. We hope K2 can follow up with us to help out, thank you.

Knew all of the options and trade-offs
5 /5
Having Elias help me really understand all the trade-offs between skis, bindings, boots, googles, helmets, and poles really made all the difference in me ensuring I’m getting exactly what I need for what I’m trying to do. I’ll be returning to Elias and Curated for life.

Nick got back to me with recommendations within 30 minutes including a video explanation, custom for me. He also kept an eye on the board I wanted to go on sale and informed me the day it did. He helped me get exactly what I was looking for even when I didn’t know exactly what I wanted to start with. Nick is awesome!

Eric has been helping me deliberate over my very first ski purchase for the better part of a year now. It's scary to take the plunge on such a steep investment, and he's been walking me through a year of trying out demo skis on my own time to hone in on my exact preferences. I couldn't have done this without him! I'd recommend his expertise and Ski sherpa'ing to anyone looking to get into or upgarde their gear. Thanks Eric!

Zach is knowledgeable, responsive and fun to shop with!
5 /5
Zach gave me a lot of information about a few different set up options that I was considering. The support and information that he shared starting with the first curated video guide he did for me, followed by multiple responses to my multiple text questions, he really helped me do my research and feel confident about my purchase. He was also very patient with me as I made my decision, but he stayed just the right amount of in touch on the shopping, so that I would eventually do the right thing for me, which was getting a new set up!

I like do lots of research before buying something, so that I feel confident in my purchase. Mila made this process so much easier! Having someone, that has knowledge about different products already, to give suggestions and feedback made me much more confident in my purchase. I am also very happy with what I got now that it's here and for a good price!

Leo helped me pick the right skis and boots
5 /5
This was my first time using Curated. Leo made the experience great and seamless. He was highly responsive and very knowledgeable. I’ve skiied almost my whole life but I still find ski equipment and associated research difficult. He made translated the jargon and made recommendations based on personal experience. He also never pushed and let me take my time to make a decision. Thanks Leo!
