Mad Rock Men's Flash 2.0 Climbing Shoe,Yellow/Black Size 5.  These were a customer return due to the sizing not being correct.  The tag on the inside of the shoe indicates these are an 8 but the measurements according to Mad Rock's size chart don't match up.  These measure 23 cm toe to heel on inside of shoe, which on their size chart is a 5.  I've included the size chart in the images.
