text: There is a very unusual &#34;hump&#34; in the arch area that made these very uncomfortable. (I have high arches and I like good arch support however this was not what I consider to be arch support) The shoe it's self was a little larger than my usual size 12 running shoe. I like to keep about a thumbs width in front of my big toe but these were a little longer. The shoe has a &#34;u&#34; shaped sole that's purpose is to help &#34;rock&#34; your foot as you strike the ground. However, I am a heel striker and this caused a very uncomfortable and unusual change in my gate that cause calf pain almost instantly. I didn't care for these and have switched to the Hoka Clifton 2 to try.
