They are comfortable, you can walk many kilometers in them. this is my second pair i wore the first pair every day for about 3 years walked a lot of miles in them finally i noticed they are a bit worn at the heel and i thought it would be better for my posture a new pair available but an old pair still beautiful and despite the fact that the heels are a bit uneven after so many years they are resilient. I am very thankful for them, the best pair of shoes I have ever had.
