I have owned the solid black, double-strap around the foot and toe (Unaweep ZX-2 ??) style of Chaco sandals for six+ years now. Although my previous pair are still in good shape, I wanted a newer, LIGHTER, and prettier pair of Chaco sandals. I bought the Yampa Z-2 in the color of Checker. I like the bluish colors in this particular sandal.

I wear a US size 9 womens and I have a high foot arch. I have not experienced any foot problems or back problems with my Chacos. I've worn my new pair twice now and they've been very comfortable. I wear Chaos for water sports and outdoor sports, but also as a quick slip-on shoe for daily activities. The "Luvseat" and "Vibram" really make this shoe comfortable!

Although I will continue to wear my previous pair on occasion, I wanted the Yampa Z-2 style for three reasons.

#1.) They are MUCH LIGHTER.

#2.) The single-strap sandal versus the double-strap sandal is MUCH EASIER to adjust.

#3.) The single-strap sandal versus the double-strap sandal is MUCH MORE COMFORTABLE around the toe, especially when the sandals get wet.

I know these shoes are pricey, but in my opinion, they are worth the money. Good luck and God bless.
