I initially started looking at approach shoes both for everyday wear and for, well, approach walks to crags. I find traditional boots clunky and often unnecessary so I wanted something lighter. After trying on a multitude of pairs I settled on either the 5.10 Guide Tennie or the La Sportiva Boulder X. I picked the Boulders. They are actually rather different shoes - I have now owned both and can compare the two - but I think the Boulders are better as 'approach' shoes in most situations. I will review both on their relevant pages.

I should state that my first pair developed a fault within 2 weeks. The sole began to peel off at the front on my right shoe. They were replaced and I've seen no sign of it recurring.

The shoes feel very well-made. They feel robust in terms of materials. The sole is relatively stiff compared to many other approach shoes. The outsole is a sticky Vibram type with a reasonably deep tread. Inside they are lightly padded, but not too much. The insole is surprisingly good and I did not replace it. The insole can be removed for a closer fit when climbing in them.

The lacing system is neat. It runs far down near the toe to hold your foot in place when climbing. It also runs around the back to snug up the heel - this does seem to work, although subtly. The laces generally stayed tied well.

They are comfortable to wear. After long use I found the tongue would sometimes slip to the side a little but it can be moved back easily. They feel supportive for walking in and the tread offers good grip on most terrain. They have no membrane and are not waterproof at all but they do seem to dry incredibly quickly from the heat of your feet.

In terms of climbing they are good. The stiff sole means they edge well. They smear ok. The toebox is narrow and the rubber rand is robust, so they torque decently in cracks. They feel supportive and lock your foot in place. They are good for scrambling or low-grade routes. Guides or instructors will probably love them as a do-it-all shoe.

Personally I believe these are a more versatile shoe than the Guide Tennies and are overall probably slightly better, especially in the UK where approaches can be wet and muddy. They also seem better made although I only ever had a fault with the Boulders! The Guide Tennies look a little dressier but for outdoor use I would probably err on the side of the Boulder Xs.
