I wanted a pair of pretty slide-on non-marking water sandals without backstraps for city/boats/camping. The Zongs were perfect. My pair arrived quickly via international shipping. The sizing chart on the Chaco website was accurate for me and while I have found Chaco styles with backstraps are true to size, the Zongs and Hipthongs are a slightly small fit but I am very glad I did not go up a size because then they would be too big and too chunky looking. The Zongs are comfortable with good support, though for hiking the backstrap styles are more stable. The Hipthongs did not suit my wider feet because some of the straps are not adjustable but the Zongs are not a problem. My Zongs still need adjusting now and then, and I have had some toe-strangling problems but overall Im very happy. I wish they made Zongs in Tamarind colour though.
