They feel great except for the fact that they eat into your foot and there is no way to adjust it.  I have a lower arch on one side and the Zigtech &#34;spikes&#34; eat into my foot making it impossible to walk without pain.<br /><br />Disappointing as these were highly rated on several sites as shoes for over weight men.  I'm on my feet and walk about 5 miles every day for work and hoped these would make my life a bit easier but sadly, they almost broke my ankle, trying to make me walk differently.
