Figured since all my other Keen shoes and sandals are size 8 and very roomy I'd order these in 8.5 and it would be just right. Nope. As others noted, STILL too small and sized completely unlike other Keen products. Returned and ordered in a 9, which would normally be clownishly HUGE for me but instead I am hoping it will be large enough.
Good thing is, easy return. I give it 3 stars for probable comfort (excellent Amazon service earns 5 stars) but deduct 2 for lack of standardization within the brand. I really don't think consistency of sizing is too much to ask of a company, especially one that makes only footwear.
