Scarpa Instinct Lace Review

Although the La Sportiva Katana Lace is our favorite all-around rock climbing shoe, it has a narrow midsole that's not suitable for all feet. The Scarpa Instinct Lace features a similar shape, downturn angle, and closure mechanism, but with wider dimensions in the midsole. If you find the Katana too narrow for your feet, the Instinct Lace is an excellent alternative.

Performance Comparison

The toe box on the Instinct Lace is longest at the center, which should improve comfort if your second toe extends past your big toe.

Edging

The Instinct Lace is fitted with 3.5 mm of Vibram XS Edge rubber at the forefoot that supplies plenty of support for edging on the smallest features. Its moderate downturn puts your foot in a curled posture that focuses extra power through your toe on both the slabs and steeps. The most significant difference between this shoe and similar models from La Sportiva is the bendy Flexion midsole and heel. This supple material supplies extra sensitivity for the back of your foot, but it reduces overall support and may accelerate foot fatigue during long, taxing leads.

You can get plenty of edging performance from the stiff forefoot of these shoes.

Crack Climbing

Although the Instinct Lace isn't designed specifically for crack climbing, it performs admirably well at the pursuit. Its wide midsole and modest downturn ensure that your feet and toes remain in a relatively neutral position, which reduces pain during torqued crack jams. Meanwhile, this shoe's technical prowess allows you to exploit marginal seams or face holds when the crack disappears at the crux of higher-end trad routes. However, we believe this shoe has two deficiencies compared to other similar models: a tall toe box and insufficient lace protection. The height of the toe box means it's harder to squeeze more rubber inside thin cracks (narrower than 0.75 inches), while the unguarded laces mean that you'll need to replace them frequently if you climb a lot of cracks.

The minimal material on the heel allowed for ample sensitivity while heel hooking.

Steep Terrain

The rubber on the rand extends to cover the top of this shoe's toe. This provides extra grip and protection for toe hooks so you can keep your body close to the well when things get truly steep. We're also fans of the heel design. It's covered in a combination of sticky rubber (black) and Flexion (orange) that together supply loads of grip without adding too much material to sacrifice sensitivity. The toe of the shoe is pointy laterally to enable it to sneak inside slim pockets. However, the tall height of the toe box is a hindrance for getting them inside some types of pockets. Overall, we think this is an effective shoe for most steep and pocketed climbing.

Although the forefoot is stiff, the Instinct Lace is fairly flexible through the midsole.

Sensitivity

The awesome edging ability of the lace-up Instinct is partially due to its stiff forefoot. This stiffness, unfortunately, reduces sensitivity by a modest degree. We were still able to detect small micro features, but the sensation is not as strong as with an ultra-soft slipper design. From the arch to the heel sensitivity is higher because the construction changes from 3.5 mm of sticky rubber to 1.0 mm of Flexion. This thinner material also gave us greater freedom to flex our feet and adjust their position to the angle of the terrain.

The combination of a moderate downturn and stiff toe box means these shoes are well-suited for techy sport climbing.

Comfort

The lacing system on the Instinct supplies plenty of flexibility to tweak to fit for different foot shapes. Our wide-footed testers were particularly pleased with the ample roominess of the midfoot that provided a welcome respite from days of testing uncomfortably narrow shoes. We were also pleased with the stiff support in the forefoot when we had to hang out on tiny holds as we tried to decipher intricate sequences above. Comfort-wise, the only drawback may be the softness of the midsole which can contribute slightly to premature foot fatigue.

Although we think these shoes perform great at bouldering, we imagine some shoppers will be frustrated with the inconvenience of lace-up closure compared to velcro.

Value

The Instinct Lace is a premium shoe with a correspondingly premium price. That's okay, though, because its performance far exceeds the cost. We think they're every bit as good as other similarly priced shoes, and we've also seen them on sale on occasion. If you're able to find them for any discount, you'll be getting an absolutely great deal.
