while the hemp rainbow do not seem to last as long as they leather version , these be super comfortable and do not develop that terrible sandal smell as fast as my leather Rainbows do . I have have my hemp sandal for about 2 year , and they be just now become unwearable . I have only buy my rainbow from the manufacturer , which be a tad more expensive but you get a warranty along the line of - if the layer separate or the strap break before the bottom wear through we 'll send you a new pair . if you look at the size chart on the Rainbows site it might clear up any size issue , all of the women size taper toward the heel , if you do not like the tapered look I would suggest buy they men sandal , which I have buy before , they be quite a bit wider than the women style . I wear a women 10 1\/2 and I usually order the l10 size from they . all in all I have have fantastic luck with my rainbow .
