I purchased these sunglasses for running.  They have a special nose pad (which may take some getting used to) that keeps the shades in place without pinching or slipping.  I run long distances and I barely felt them on my face (and they did not fog up).  I am a girl and they are not big on my face and have a nice wrap around frame.  The shades themselves are cool looking, I have had several compliments about them.  For the price and quality jimarti shades can not be beat.  I know this is a product review only, but this seller is top notch when it comes to customer service and class.
