If you have a narrow toe box, these are the shoes for you. They’re a bit heavy but well made, and have a nice stiff and grippy sole. Unfortunately for me, the toe box was wayyyy too narrow and I don’t even have a wide foot. I even sized up a half size and they’re still too narrow. I have the TX4’s as well and that toe box has plenty of room, they’re almost too wide. I’m not sure why la sportiva makes such a huge variation in their shoes.They were so painful I had to take them off in the middle of a long class 5 scramble since the circulation in my toes was completely cut off. I wish they fit as they are much more rugged and durable than the TX4 (the TX4 lace system is extremely delicate and frays/breaks) and I really like the stiff platform. Maybe the next version of the boulder x will have a little more width in the front (hint hint la sportiva). So for now they get three stars for having an unusually narrow toe box that makes them unwearable for me.
