In this case, the rugged silicone skin bears more of a resemblance to underneath a tire rather than a tennis shoe sole. It has 6 mm of silicon shock for the four corners, and it has 3 mm of overall body shock protection. Again, there is no waterproof protection, but there is black flash ring to show pictures without glare.
In all honesty, I had a hard time getting this case around an iPhone 5. You have to peel it off after you take it out of the box. Hey, this is a good thing. So with the silicone outer coating with the replaceable screen protector, this Shockdrop is an appropriately-named protective covering for the iPhone 5.
You can get it on the Hard Candy site for the iPhone for about $39.95.
