If you’re looking at resoling your climbing shoes, you’ll run into two types of Butora rubber: Fuse and Force. They’re not just labels—they're two very different compounds, each tuned for specific climbing styles.

Butora Fuse: Grip and Sensitivity

Fuse is Butora’s soft, ultra-sticky rubber. It excels on steep overhangs, indoor comp problems, and polished gym volumes where friction is everything. You’ll feel every surface underfoot—great for smearing, toe-hooking, and trusting marginal features.

The catch? Softer rubber wears down faster and doesn’t edge as precisely. If you drag your toes a lot or spend time on sharp rock, you’ll burn through it quicker than harder rubbers.

Choose Fuse if you:

• Climb steep routes or boulders

• Spend most of your time in the gym

• Want maximum grip and feel underfoot

• Don’t mind trading some durability for performance

Butora Force: Structure and Longevity

Force is the firmer, more supportive option. It’s less sticky than Fuse but offers better edging and shape retention. That makes it ideal for vertical face climbing, outdoor routes with small holds, and longer days where your foot needs more support.

It holds up better to wear and tear, too. If you're climbing outdoors often or want your shoes to last longer between resoles, Force is the more practical choice.

Choose Force if you:

• Climb vertical or slabby terrain

• Need solid edging performance

• Climb outdoors often

• Prefer durability over maximum stickiness

Which One Should You Get?

It comes down to this:

If you want stick and sensitivity, go with Fuse.
If you want support and durability, go with Force.

Final Thoughts

Butora didn’t just slap two rubber names on their shoes for show. Fuse and Force are legit performance compounds, each tuned to a specific type of climbing. Know your style, know your terrain, and pick the rubber that works with you—not against you.
