Normal wear on five ten freeriders?
How often do you ride? Short answer, yes this is pretty normal if you ride quite a bit. Shoes designed for use with platform pedals tend to have softer soles to improve grip with the pins. Unfortunately softer also generally translates to faster wearing. 

In addition it looks like those particular pedals have a bit of a hollow portion to the pins, whether it is an allen wrench relief or otherwise. (My eyes aren't good enough to tell) I have found pedals that have an indentation or hollow portion in the center of the peg tend to tear up shoes a bit faster as they act like a sort of cookie cutter. 

I have sense changed pedals and shoes on my MTB for similar reason. I find using a decent flat bottom skate shoe such as globe, etnies, DC or other similar style works just as well for me and i don't mind the slight difference in grip for general trail riding. Dirt jumping or similar you may feel the extra grip is worth the expense of wearing out shoes quickly. 

I have also found Shoe Goo or similar works quite well for extending the use of such shoes once they start to wear. It seems to be pliable enough to work well with pinned platform pedals.
