Seems better for hiking, not trekking - La Sportiva Nucleo High GTX Hiking Shoes - Men's

This is moderately-priced boot that appears to be well constructed. The sole has a lot more flex than a trekking book (like the Trango), so probably better suited for hiking. Unfortunately, the toe box seems a little narrow and consequently the boot feels like it constricts the top of the foot. It helps that La Sportiva uses European sizing, with half-sizes available, so there are more sizing choices. However, it's too bad that La Sportiva doesn't make their boots in wide sizes.
