I took advantage of a promotion offering me my first pair of Birkenstock, and it will surely not be the last ... Everyone knows the name brand, but I had never dared to put this money in a pair of "flip flops". Yes I fell because I spend a lot of time in sandals, and I always some problems to find a pair that takes my 40-41 well enough (I have very thin feet). I chose the 40 narrow, and it is PERFECT! Comfort and held await you! If the pair keeps me two years - what appears to be a minimum if I believe all the rave reviews, while the sum made will really pay for itself! Amazon thank you for your quick delivery and careful, and your ultra competitive prices :-)
