Running Shoe Terminology

Thanks in advance for all the help.

I am just wondering if anyone else has noticed this in certain running shoes? I tried on a few pairs of Skechers a few years ago and noticed a very noticeable, angular drop from the heel to mid foot in the shoe. I have now just tried on another brand and noticed a similar feeling. Are my feet just sending bad signals or is there an actual design feature that I can learn more about if I search under the correct terminology?

Take care,
Larry
