[Flip FLops Sole Details]

Hi Guys! : D
How could I avoid that the edges split as shown in the image bellow?
I`m using microdisplace with a different map and settings for each part of the sole (bottom, top and side) … have no idea how to make the transition between the three textures look more smoothly.
Any tip and advice are very wellcome!

Maybe give the top and bottom some depth. Just the smallest amount. Like select the top and hit E then enter or a small amount of Bevel.
