These shoes saved my feet, knees, ankles and back on my backpacking trip through Europe. I have very flat feet and most shoes force an arch in my foot, which ends up getting very sore. To take pressure off the part that hurts I walk on the outside of my feet which then throws everything off and I am a mess. These shoes, however, were perfect and I never had any issues. In fact, in the 17 days I spent in Europe I walked almost 150 miles. I will definitely buy another pair whenever these wear out, however that won't be anytime soon. Great quality product!
