  • When Jason Kehl FA’d his ultra-modern v13 test piece, “The New Zero,” in Southern Illinois, it marked a new level for Jason and a new benchmark for technical climbing.

    Inspired by this commitment to pushing boundaries, The New Zero was born. A new performance benchmark for So iLL shoes and for your climbing.

    The New Zero boasts the performance of a sensitive slipper with the stability of a strapped shoe. One of the most soft/high performing shoes in our line. The New Zero performs on steep overhanging bouldering as well as the smallest of smears. Designed for advanced and elite climbers, The New Zero allows for full sensitivity to nuanced footholds and technical bouldering demands.

Great all around Shoes

I started wearing this shoes after I had an accident were I tore my ACL.
I used to climb with the miura vs, and I feel like with this shoes I have the same precision but they are so much more confortable and much better for smearing. I am yet to take them to the rock.
I would recommend them to those who are transitioning from a beginner shoe to a more aggressive one.

New Favorite Shoe

I have worn several brands and this has been the first shoe that took one route to break in. They are absurdly comfortable, sizing was dead on, super sticky rubber. Been using these 3-4 times a week for about two weeks now and have had zero issues only great climbing and comfortable feet. Also love the mesh bag that comes with these.

Rev it up

It’s so nice to have a climbing shoe that feels just as precise and aggressive from the first climb to the last. Wanted a more aggressive shoe for bouldering that would not stretch out due to sweat and I got more than I bargained for. Long break in but now it’s like wearing socks. Super grippy and smooth. Will never go back to the other guys.

Perfect first impression

These shoes is by far my new go-to for indoor clims. Excited to try them outdoor when spring hits Scandinavia (June)

Comfortably Impressed

Title says it all.My first soft shoe after The Runner. Great fit out of the box and I cant wait for them to break in. Great stickyness tho I do believe they will wear down faster but time will tell. Cant wait to try FRP and NZPs after this!

Perfectly Soft

The synthetic vegan upper fits like a slipper, and the fabric is normally used on the inside of durable work boots in the footwear industry. For a shoe at this level, it is incredibly comfortable. The thread we use for the upper is specially made in the southeast as one of the softest threads in the world, and cannot be felt in the toe box. This shoe is sensitive and every detail matters when performing at a high level.

No Hot Spots

Dark Matter toe rubber meets the rand by butting up together, with no overlapping. This is incredibly hard to do in production and provides no hot spots.

The New Zero is coated in "Dark Matter" rubber, part of the "UnParallel Rubber" family, a sticky outsole rubber originally formulated for the United States Navy Seals to ensure security in foot placement during approaches. It's the stickiest rubber you will experience.
