Who should buy the La Sportiva Boulder X

The Boulder X is a product of past-yet-proven technologies combined to give hikers and climbers footing security like never before. It's for you if:

  • You want something that performs amazingly on edges and in cracks at the same time.
  • You're a huge fan of the Mythos, and you want the same fit in your approach shoes.
  • Approach hikers that don't cost an arm and a leg attract you.
  • You do a lot of smearing on your way to your climbing spot.

Who should not buy it

With no negative comments about its laces, the Scarpa Mescalito is a great alternative to the Boulder X. Also, opt for the La Sportiva TX4 if you're looking for something glove-like minus the narrow toe box.

The La Sportiva Boulder X's double-edged lacing system

The shoe's closure can be a pretty polarizing thing. On the one hand, it delivers a kind of fit that channels the confines of the La Sportiva Mythos (a good thing, especially for fans of said climbing shoe). On the other hand, it's been the subject of criticism, either for its extreme length or high tendency to come undone.

La Sportiva Boulder X vs. TX4

In terms of structure and features, the Boulder X and the TX4 have quite a lot of differences. This section lists and describes the components of each offering.

Midsole. The Boulder X has extra cushioning for long approaches in the form of a layer on top of the insole. It also has a shock-absorbing EVA midsole. As for the TX4, The MEMlex midsole with STB Control System delivers enhanced support and torsional rigidity.

Upper material. Both approach shoes are made of leather. Although these shoes have full randing, the Boulder X comes with a slingshot rand, which enhances fit. As for the TX4, its rand is part of the STB Control System, which works with the midsole to give the shoe a more solid structure.

Outsole. The common features between the two are the Impact Brake System and the circular lugs on the outsole. As for the rubber compound, they differ. The rubber of the Boulder X uses the Idrogrip, while the TX4 uses the Megagrip. The outsole of the latter is also built with an enhanced stability area and comes with a more pronounced heel brake for extra stopping power. 

Fit. The Boulder X has a regular width overall. On the other hand, the TX4 is wide in the toe box area.
