Update (November 2024): Nitro (vegan) is Discontinued.

A combination of the wonderful upper of the bestselling Waterproof Boulder Boot, and the grippy, lugged outsole of the Outlander, the Boulder Summit is a great option for winter conditions.

All versions feature a fully waterproof lining, which we've found holds up well over time with similar waterproof models from Lems. Leather maintenance and protective treatments suitable for Nylon will keep your Summits looking and feeling great even longer.

While this boot itself is zero drop, as of June 2024 the optional insoles have a small drop (1.5mm for the Minimal Cork insole or 3.5mm for Adventure Poly insole). 

• Lems suggests that the insoles compress over time, so you may not notice a drop after the shoes are broken in.
• If you prefer not to use an insole that has a drop, you can wear these without any insoles, or try a zero drop insole such as our Alpaca Insoles.
