Thankfully the first-gen Raggmo was still available, I returned this new version for the Raggmo 1 in the same size that fit as expected.  I had a worn out pair and thought this Raggmo 2 would be an improved upgrade.  Sadly Adidas missed the mark with this one, and additionally the pair I got was brand new and was already separating at the heel between the foot bed and out sole.  The foot bed feels too small and narrow, and the thong straps are very tight compared to the Raggmo 1.  Stick with the original.
