    MerinoGrey Insole

    Superfeet took their well-known support and performance and combined it with the equally legendary natural thermoregulating properties of merino wool to create the MerinoGrey Insole. The thick pile of the 90% merino top cover lays over the insole's supportive Foundation foam and Encapsulating Stabilizer System to keep you supported, aligned, and comfortable. Trim these insoles to fit and slip them into any hiking, walking, snowsports, casual, or military shoes to boost their support and deliver cushy, breathable comfort.

    • Foundation ultra-light closed-cell foam resists moisture and helps reduce shock while offering advanced comfort
    • Unique stabilizer cap offers optimal underfoot support with a deep heel cup that cradles the heel's fat pad for improved natural shock absorption
    • Exceptionally soft merino wool layer offers extreme comfort, moisture wicking, insulation, and breathability
    • Wool top cover 90% recycled, combining leftovers from wool sock production with virgin merino wool
    • Trim to fit any roomy footwear
    • Item #SFT0017

    Not very comfortable

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Height: 5'4"
    • Weight: 150lbs

    They were unfortunatelly too thick for any of the shoes I wanted to put them in and would lift my feet up awkwardly high against the top and make it so they would no longer fit properly.

    Great winter insole

    • Height: 5'10"
    • Weight: 170lbs

    These are great! I have several pair. They wear really well and don't wear out too fast. I like the fabric on them - it doesn't tear up your socks for soles like some other rougher fabrics which is nice.

    Great product

    • Familiarity: I've put it through the wringer
    • Size Bought: 9.5-11M
    • Height: 5'9"
    • Weight: 165lbs

    These soles plus better socks, solved my blister problem. I bought these for the Three Pass Trek in Nepal and they were warm but not too hot, wicked sweat, and provided great cushion and support for a 14 day hike. I have medium arches and they seemed appropriate. Also interesting to note, as it may affect those with larger feet, is that I bought these in the men's 9.5-11 and my Lowa Vantage GTX boots are 10.5's and the insoles fit perfectly, didn't have to cut them.

    Perfect Solution

    • Fit: True to size
    • Size Bought: US 9.5-11

    I bought the Blundstone Dress Series Boot and I ended up ordering them a little too big. I decided to try them with a pair of insoles and bought these because of Merino being naturally anti microbial and the temperature regulation factor. I love them. The insoles made my boots fit perfectly with the original insoles still in the shoe and a light pair of socks or a thick pair of socks and without the original insole. So I like that this gives me options as well. I'm very happy with my purchase and doubt this will be my last pair of Superfeet insoles.
    My boots are a size 11 and I didn't have to trim these insoles at all.

    Support and warmth

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: F
    • Height: 6'4"
    • Weight: 190lbs

    I've used these in my Rome Libertine Snowboard boots for the past two season and LOVE them. I have over 100 days on these insoles and they are still holding strong. I plan on getting new snowboard boots this winter and will definitely be buying these again.

    Foot Sauna

    • Familiarity: I've used it several times
    • Fit: True to size

    I have been using Superfeet for around 10 years in footwear that I wear when carrying heavy loads (Backcountry Hiking, Military Rucking, Skiing) but this year I grabbed a pair and tossed them in my AT boots. I have not had any one item change my comfort so significantly. These things provide perfect arch support and the wool keeps my toes toasty warm. Then when I get back to the hut I can pull them out and they dry incredibly quickly, ensuring the same comfort the next day. I highly recommend these.

    Merino is money!

      When these came out I was itching to get on board, because I use Superfeet in all my shoes and I swear by wool's versatility as a technical fabric. I put them in a brand-new pair of GORE-TEX Danner hikers, thinking that while they might be too warm for summer, they'd be perfect for winter. However, I found out during an 8-mile hike in 65-70 degree weather that these footbeds are comfortable in warmer temperatures too, even with leather uppers and thick hiking socks. They are warm, but not too hot, and they never felt damp or sweaty. In fact they feel strangely (but not unpleasantly) neutral, as though they are insulating you from the ground (they are). The felt top is luxurious, softer than I expected it would be, but not too cushy or at all unsupportive. I wouldn't recommend them for low-volume shoes, as they are pretty thick, and I can't say I'd imagine they'd be as comfortable in really hot or humid climates, but so far they appear to be perfect for my uses. Can't wait for the snow to start falling so I can feel how well they perform in the cold.
