I really love these shoes.  I live in Thailand and live in flip flops.  I have 8 pairs of Sanuk.  I really like these as they are a little narrower (I have narrow feet) and look slimmer on my feet than some of the others.  I  wear an 11 1/2 in regular shoes, but order a 10 in Sanuk flip flops.  My only complaint is that after a year or so of constant wearing the soles start to develop holes in the footbed.
