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.

Desired Fit Can Depend on Experience and Performance

• If you boulder at V4 or climb at E3/4 or less then So iLL recommends you to buy a larger size than your normal shoe size by around 1 1/2 sizes. Example: if you normally wear a size 8 trainer we would suggest a 9 1/2.
• If you boulder V5 or climb regularly at E4/E5 and above then So iLL recommends you buy a larger size than your normal show size by around a 1/2 size. Example: if you normally wear a size 8 trainer we would suggest a 8 1/2.
• This is a guide only and the size that suits you will depend on your foot shape such as high or low volume, wide or narrow foot etc. For multipitch routes you may want to have a more relaxed fit and size up a little. So iLL recommends you check the fit before wearing outside or at the boulder wall as we can't exchange any shoes showing any signs of being used.
