My coworker first told me about Ecco shoes which eliminated his foot (sole) pain. Ecco shoes are light, well constructed, extremely durable and comfortable. They are well padded, require no break-in period and no blisters from day one. (no more band-aid on Achilles tendon)  For my other 2 pairs of Ecco shoes, I am amazed that outsoles show little wear and no sign of uneven heels after more than 3 years of frequent use. I had gone through 40+ pairs of shoes, mostly due to uneven and worn heels on the outside, in the past 3 decades. Because these shoes last much longer and I can wear them everyday and just about everywhere, they are well worth the price I paid, about $95 to $130 on-sale. I have bought only Ecco shoes to replace my semi-dress and casual ones in the past few years.
