Query: Size 5.5

This is only the 2nd pair of thongs I've ever owned because the toe area always hurts after awhile. The toe strap is made of soft material and so far it's been comfortable. I'm a size 5.5 and tried both sz 5 and 6. Sz 6's length fits slightly better but the strap is a bit too loose for me so I went with sz 5. The only thing I don't like about it is that it makes a flapping noise when you walk. Well, I guess most flip-flops do. The pros are cushiony foot bed and extremely lightweight so great for traveling.
