I love the thinner double strap Chaco over the thick single strap! I think they are cuter but it is all peraonal preference. I will say as much as I think the big toe loop makes the sandal more attractive, on both my single strap and double strap it would always get tight and I would try to loosen it every time and seemed to make no difference. For my next pair I plan to get the style without the toe strap. I have these in 2 very different sizes and have found that interestingly enough my 7Wide in womens fits better than my 8 1/2 regular. My 8 1/2 will give me hot spots in my arch but I have backpacked over 20 miles straight in my 7 wides no problem. So with that being said make sure you have the best size for YOUR feet to have the best experience!
