I have original arbpros and love them. The sole is different, but I am pretty sure they are not designed to be resoled. Haven't see the EVOs in person, but I don't think I like the look of those soles as well. They don't look like they are designed to be resoled either. Touch base with treestuff to ask them if they can be.
Other thought: I change into my Arbpros as I am getting ready to climb, and take them off when I am going to be doing a lot of ground work. My hope is not only that this makes them last longer, but it will keep them cleaner/less slippery to use in the tree. They are great in the tree, but honestly not as comfortable for walking around in. I have Keen hikers that I wear just around or Chippewa steel toes if I am using a chainsaw on the ground. The steel toes and arbpros stay in the truck all of the time and go on and off as needed. It is a pain sometimes, but nice to always have the right boot for the right occasion...keeps my feet comfortable and I think it is safer. Might take a total of 3 minutes out of the day.
