this be my second pair of rainbow sandal , and I believe I will continue to be a loyal customer to the brand . you will not find a better quality sandal -lrb- and they guarantee a new pair if the old pair ` break ' before you wear through the sole ... check website -rrb- . the only reason I get rid of my old pair be mold ... and it be my own fault . they be leather , I would use they in water and then not properly washed\/dried they . this be my reason for hemp this time around . I must admit that the leather be slightly more compfortable , but the hemp be still better than any of that synthetic bologna . be prepare for you skin to be rub raw the first time you wear they for a long walk ... but after you callus up , it be smooth sailing . such be the life of a sandal wearer .
