Have only had these Teva sandals for a few short days, but wow, they are super comfortable, and they appear to be very well made. My biggest concern was the size!!  A few had stated that they ran small and to go up a size!  I went to the Teva website and they have a sizing chart.  I normally wear a 8.5, but due to  wide foot, usually go with a 9.  My previous sandals were a size 9 made by Dunham and they were great and lasted for over 7 yrs!!  Would still be wearing them except a puppy decided he should chew on them!  I went with a size 9 in these teva's and they fit very well. These teva's are a tad bit smaller than the Dunhams, but they still fit!!  Very happy with the purchase!!  Love the speed buckle!!

Still love them, and they are holing up great!  Loved them so much--just recently bought a 2nd pair to keep in storage!!  But my current pair show no signs of breaking down and I wear them every day (Live in the tropics)
