The New Zero

This shoe is in Men's sizing
  • 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. The softest, highest performing shoe 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.

Ill never use another shoe besides SoIll

Went from the streets to the Zero and I loved em both had an issue with the streets stickin to the holds on on V5s and up but the Zero have been absolutely amazing


These things are pretty sweet. I like them in the gym but will mostly save them for outside. Fit suuuper snug sizing guide helps. Little to no dead space in the whole shoe witch I thought was impressive. I was weary of Soills shoes for a while I won’t lie but I’m eating my word now. Really like how it’s made here. USA!! USA!! USA!!! Haha

Pretty Sick

These shoes are pretty much everything I look for in a climbing shoe. They're very soft and sensitive, the rubber is hella-sticky, and they fit my foot well. My only initial concern was the security during heel-hooking, but since the velcro patch is basically a big triangle you can just strap them up a bit higher on your foot and they don't go anywhere. They smear, hook, and scum pretty well, at least on the sandstone down here in the southeast. Overall I'm pretty psyched on these shoes. For sizing reference, I typically wear an 8.5 or 9 street shoe, size 8 Dragons, size 38 Skwamas, and ordered a 9 in the New Zero, and it fits perfectly.

Ready to go

These are the first shoes I’ve put on that I could wear straight through on their first session. The quality is not compromised by their ready to wear comfort.


This shoe feels great right out of the box. Tight to fit but also comfy. Feels great climbing in them too.

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.
