“It’s more compact than the previous version and integrates the sponge, making it super easy to use! The shoe grip improved significantly, and thanks to this, I achieved a 5.03-second record in Kyoto! Definitely give it a try!”

"After applying, I could confidently step on previously slippery dual holds and thin volumes—really felt the effect! It’s not a cheap product, but I recommend using it for competitions or must-send problems where results matter.”

“It’s so easy to apply right after climbing and keeps the sole’s friction in perfect condition. I’d been unsure how to maintain my soles, but this is great. Since it doesn’t dirty my hands, I can apply it right away. The pen type is compact, so I can carry it with my shoes. Seems great for running shoes too!”

“The biggest improvement is that the grip-applying sponge and container are now integrated. This greatly simplifies applying it to the sole—and no more worrying about losing the sponge! Just remove the cap, turn the dial on the back to dispense liquid, and apply it like drawing with a pen. It’s about the size of a marker, so it’s very portable. As for grip, while it takes slightly longer to dry than the previous model, it penetrates deeper into the rubber, making the effect last longer. It’s great not only for enhancing grip before climbing but also for preserving rubber performance afterward—apply Sole Energy before storing your shoes!”
FAQs
-
Sole Energy is our proprietary formula that acts as both a solvent and a nutrient for the rubber—removing oils, oxidation, and chalk that degrade performance while restructuring the material to restore and even enhance its original grip. Unlike surface treatments, it penetrates deeply into the rubber for a lasting effect.
-
While the effects of Sole Energy can last for multiple weeks, we recommend reapplying it after each climbing session to maintain peak performance and extend the life of your rubber.
-
Sole Energy contains no adhesives or hardening agents—it simply restores and enhances rubber performance without increasing wear on climbing holds.
-
Sole Energy does slightly dissolve and restructure the surface layer of rubber as a part of its restorative process, but the effect is controlled and minimal. It doesn’t cause any meaningful wear or damage.
-
Before using Sole Energy, wipe off any chalk from the sole, turn the rear dial to saturate the sponge tip, and apply evenly. Let it absorb for about 15 minutes, and you’re done! We recommend applying Sole Energy after every climbing session.
-
Unlike rubbing alcohol or soap and water, Sole Energy doesn’t just clean the surface — it nourishes and restores the rubber itself. While alcohol and soap can dry out or harden soles over time, Sole Energy penetrates deep into the material to rejuvenate flexibility, grip, and friction performance, keeping your shoes feeling and performing like new.
