Fit and Function

I received a pair of the Crew and Mini Crew Minus 33 Micro Cushion Wool Socks for testing.  I’m a size medium on the Minus 33 size guide and found that the Minus 33 Micro Cushion Wool Socks fit true to size.

I’ve been wearing the Minus 33 Micro Cushion Wool Socks on a multitude of adventures, ranging from hiking, trail running, mountain biking, weight lifting, and general living.  The fit of the socks is spot on.  The sock feels supportive, thanks to the 3 Zone elastic.  I also think the level of cushion is good, especially for hiking or longer days on your feet.

While being constructed from a wool-nylon blend, the Minus 33 Micro Cushion Wool Socks feature construction that helps with wicking and breathability.  The venting that’s designed along the top of your foot consists of a thinner, stretchier knit, that helps keep your feet from feeling too warm.

I also appreciated how the sock stayed in place, even during a hike with SUPER steep sections.  This helps prevent blisters and overall discomfort over long distances.

The knit of the sock cuff is also nice.  There’s a good balance of stretch and compression.  The socks are sturdy enough to hold up to pedal strikes and clean up nicely after time on super dusty trails.

Best of all – the Minus 33 Micro Cushion Wool Socks come in a wide range of heights, ranging from no-show to over the calf. It’s easy to pick a sock, or range of socks, to fit your style and needs.

Somewhere along her triathlon journey, she picked up deep love of cycling. Cycling encouraged her to see landscapes in a new way, learn new skills and to develop self reliance; now she often goes and does Type 2 rides just to see if she can do it.  She’s got all the bikes: gravel, mountain, fat bike, time trial and road.
She is even known to combine her love of camping and cycling and go off on solo 24 hour overnight bikepacking trips in the mountains of Colorado. In addition to bikes, she teaches yoga, lifts weights, skis, SUPs and has recently purchased a campervan.

Erin is a former Montana park ranger with a degree in environmental engineering.  She loves getting into technical details while putting her gear (and herself) through the paces. She shares her home in Colorado with her husband, Will, and her 3 cats (Zipper, Brewtus, and Simcoe).
Fall and winter 2025 will bring Erin to the “Adventure Side”, with many camping, vanlife, bikepacking, and mountain bike rides. Once the snow flies, she can be find resort skiing, fat biking, and triathlon training (inside and outside).
In 2026 Erin took the National Championship in her Age Group for the USA Triathlon Cross Tri. She’s also racing the a National Championship Road Sprint and Olympic Distance race in Milwaukee and a few other off road triathlons and bike races.  In 2027, she will represent Team USA at the World Championship Cross Triathlon in Edmonton, Canada. She’ll also save lots of room for adventure time with her friends and husband.
When not adventuring, she can be found on a sunny patio somewhere, drinking beers with her husband.
