This company makes a variety of different sandals (and now shoes) that are sturdy, comfortable, good looking versatile. Recently they sent me the ZX2/Yampa Sandal to test.
These were my only outdoor shoe on my recent one-week trip to the Azores where I went bicycling, light hiking, and kayaking as well as doing plenty of walking on cobbled lanes in the towns and villages, and along sandy stretches of beaches. The Vibram sole with lugs performed well under all circumstances but one: moss- or algae-coated rocks. But I've found that only my ultra sticky-soled 5-10 hiking boots are the only ones that kept me from slipping under these circumstances.
These sandals are stylish when worn with a dress or skirt but are also plenty rugged for all my adventures on this trip. (I like the versatility of the black straps but other models come in a variety of patterns and bold colors.) Most importantly, they were oh-so comfortable, especially along my arch which ordinarily would be fatigued after a long day of nothing but walking. And, while I know many people find a toe loop uncomfortable, I loved the security it provided.
A negative about Chacos is they take a bit of tweaking to get the straps to fit. And, perhaps I'm a bit challenged because the accompanying directions illustrating how to loosen and tighten the straps only made things more confusing. Furthermore, it seems the main tightening strap (along the buckle side) is way to long for my feet. No worries, though. I simply had my talented shoemaker cut and resew the strap. So these negatives were easily taken care of with the slight expense for the alteration.
When I head to Southeast Asia for a month of travel, I'll be bringing along one of my Chacos as well. And, despite the fact that I'll be away for a month, I won't be checking luggage.
