Here is the detailed feature breakdown of this La Sportiva Boulder X Shoe:

Weight and Packability

At 2.2 pounds, this versatile shoe falls slightly on the heavier side. With the additional weight, the footwear offers much better foot support for carrying heavy loads and also aids in the increased durability.

Though the extra weight equals added support and longevity, you have to make a compromise while clipping the footwear to the back of your harness or packing them into a small climbing pack.


As the Boulder X is moderately stiff, it stands comfortably on medium-sized edges but doesn’t have the required sensitivity for small edges. Though the lacing system can be cinched down for better edging, the footwear has limited edging ability in tiny edges.

Similarly, the toe shape of this shoe is a bit more rounded than the top edging performers, making it a wrong choice for edging in pockets. However, the shoe does offer great foot support for standing on medium to large edges all day.


Though this climbing and hiking footwear feels big and clunky on your foot at times, there is enough forefoot flexibility to get a consistent smearing performance out of the Vibram Indro-Grip sole. The rubber and tread pattern on this climbing shoe is a great hybrid that aids with a balance between climbing performance and solid traction on the trail.

Climbing Performance

Overall, the stiffness of the shoe has both positive and negative effects on the LaSportiva Boulder X’s climbing performance. Though it helps prevent foot fatigue and also provides excellent support, the stiffness compromises the shoe’s ability to smear. However, another positive aspect to look from this is that the stiffer sole makes edging feel more secure.

Hiking Performance

This shoe from La Sportiva is comfortable for hiking as well, especially over rough terrains. The inclusion of Vibram outsole offers plenty of traction in dirt, mud, and scree. With the added weight and stiffness, the footwear can be able to edge in Spring snow better than lighter weight models.

Impact Brake System

Another great feature of this versatile shoe is the use of the Impact Brake system. The Impact Brake System helps to reduce up to 20% of the impact forces acting on your feet, legs, and back with each step while walking on uneven ground.

Comfort and Fit

The removable insole of this Boulder X has a nice amount of cushioning. Under this insole, there is a 2mm polypropylene insole, then a Micropore EVA midsole, and a Vibram Idro-Grip V-Smear with Impact Brake System outsole. These factors offer a lot of support underfoot that leads to less foot fatigue after tiring days on rugged terrain.

Moreover, the long lace of this shoe passes around the ankle collar and goes down to the toe through tunnels of leather. As the laces zigzag back up from your toe, they exert a pulley-like force, letting you adjust the fit at the ankle collar and the forefoot. One drawback of this product is that the leather tongue is not gusseted to the upper that creates breathability issues.


The La Sportiva Boulder X Shoe is known for its excellent durability. The La Sportiva Boulder X is one of the rugged models of approach shoes available on the market that features great materialization and superior sole construction. With that, you can find the footwear in excellent condition even after some great miles of scrambling and climbing.

As we mentioned already that the Boulder X features Vibram Idro-Grip sticky rubber, it helps to keep the shoe sticky even in the rainy season. The upper is extremely durable as it is made with Roughout leather and has double-stitched seams.
