Reasons NOT to buy:

User Reviews

  • The plastic portion of the BOA wire at the top of the shoe can dig into the top of your foot during a walking motion, causing rubbing and pressure.
  • Some reports of the BOA system breaking.
  • Inner boot can rub against the center of your foot.
  • These are not the most inexpensive option compared to the competition.
  • Not wateproof all the way up, and just waterproof to about ankle height.

Expert Reviews

  • Less stiff and less technical than similar models, like the Spatnik.
  • The BOA system is hard to repair on-the-go.
  • Sizing may run a bit big.


The La Sportiva G2 SM Mountaineering Boot is an easy-to-adjust and lighter-weight boot that is best suited for alpinists who prefer an easy-to-use boot with proficient warmth, instead of a more technical and stiff option. A potential issue with the BOA wire digging into the top of your foot may reduce the comfort value of this boot, but this problem only affects some users and many other users never experience this issue.
