If you’ve ever had your climbing shoes resoled or spent time comparing models, you’ve probably come across two of Vibram’s most popular compounds: XS Edge and XS Grip. They’re both high-performance rubbers trusted by climbers at all levels — but they’re not the same, and choosing the right one can make a noticeable difference in how your shoes perform on the wall.

Here’s a breakdown of what sets them apart, how they behave under different conditions, and which rubber might suit your climbing style and terrain best.

The Basics: XS Edge vs XS Grip

At a glance:

Vibram XS Edge: Engineered for Precision

XS Edge was designed to handle micro-edges and sharp footholds without rolling or deforming under pressure. It’s slightly firmer than other rubbers, giving it a more supportive and stable feel when standing on tiny features.

Key Features:

• High deformation resistance: The rubber holds its shape under pressure, which means it won’t “mush” out when you’re standing on a dime-sized edge.

• Ideal for edging: Perfect for routes where precise foot placement and balance are key — think vertical sport, technical trad, and granite slabs.

• Longer lifespan: The stiffer formula typically wears more slowly than softer rubbers, especially on outdoor rock.

Best used for:

• Multi-pitch and trad climbs

• Vertical and slightly overhanging sport routes

• Granite, limestone, or any terrain that rewards exact footwork

Vibram XS Grip: All About Stickiness

XS Grip is softer and more flexible than XS Edge, which gives it excellent surface contact and maximum friction. It conforms to the rock (or plastic) more easily, making it a go-to for smearing and overhanging terrain where raw stick is more important than rigidity.

Key Features:

• Superior friction: Ideal for slopey volumes, gym problems, and polished rock.

• Soft and sensitive: Gives you a better “feel” for the surface underfoot, which is especially useful for technical indoor problems or steep outdoor boulders.

• Faster wear: Because it’s softer, it tends to wear down quicker — especially if used on sharp, abrasive terrain.

Best used for:

• Indoor climbing and bouldering

• Steep or overhanging sport routes

• Footwork that relies on smearing or toe scumming

How to Choose: Match Rubber to Climbing Style

If you’re resoling or buying a new pair of shoes, the right rubber depends on your priorities:

• Need max support for edging and long pitches? Go with XS Edge.

• Want top-notch grip for dynamic movement and gym climbing? Choose XS Grip.

• Climbing a mix of styles? Consider the model of the shoe and where you climb most — many shoes come stock with one or the other for a reason.

Also worth noting: XS Grip and XS Grip 2 are sometimes used interchangeably in conversation, but XS Grip 2 is the slightly upgraded version with better performance overall — if you’re buying new, it’s likely you’re getting XS Grip

Final Thoughts

Both Vibram XS Edge and XS Grip are excellent rubbers — it’s not about which is better, but which suits your needs. If you’re resoling a shoe and unsure which way to go, feel free to reach out.
