The materials used in the Luna Sandal are top-quality, and the sandals should be durable enough for many hundreds of miles. Walking in them will require a somewhat different stride that you are used to in trail runners. There will be less of a heel strike and your foot placement will not be so far in front of you. There will be other adjustments to get used to, and some stabilizing muscles may become sore.
Here's another variant on the huarache style: the Unshoe.
The advantages of such a shoe on the PCT, or parts of the PCT, are:
- very light weight
- almost negligible drying time (great for stream crossings)
- better ventilation for hot conditions (blister prevention)
I hope to get a pair of these before my summer thru-hike in Europe and try them out a bit.
