I recently picked up a pair of CT520's because my size 14 lavers were too small on me and Adidas does not make sizes larger than that. So, I decided to go with size 15 CT520s. I heard they were shreddable right out of the box, which they are, but not for me. The clippers were a bit too rolly for me to play with so I decided to modify the shoe. I did similar mods that you would do to Lavers. First mod is to add a clipper rail. There is a rather large 'hole' on the instep which can make clippers roll off easier. After experiencing rolly clippers, I decided to make the rail. Heres now. You take Shoe Goo (found at common department/hardware stores for $5 a tube) and lay a thick bead of it along the deep hole on the instep. You wait a few minutes for it to settle, then add another thick layer on top of that. Then, after 10 minutes it shoulnd't stick to your fingers when you touch it, so now you can mold it into place however you like. I added about 4 layers to even it off, and it took overnight to fully dry. The next mod I did was to remove the inner layers on the instep. The instep material is pretty thick, so removing this is a huge benefit. Basically you trim around the inside like you would mod canvas out of lavers...its pretty easy to come off so you just pull all the layers off with your hand. There will be a little bit of thin foamy stuff that might remain but that isnt to worry about, just pick it off. Next you will need to remove the "N". This is quite difficult and tedious, but is worth it. There is a canvas N on the outside of the instep and a canvas N stitched onto the inside of the instep. Basically you want to just cut the stitching along with sides of the N and slowly pry it off. There is tooooons of tightly packed string and the N 's are glued down so this will take a while but should come off easily if you do it right. You do the same thing underneath the toe box except its 10x easier. Just cut along underneath and pull it out. Takes about 1 minute for both sides. After that you will want to cut the stitches holding the toe rails down just like on lavers. Just lace them up like you would with lavers (lacing method on HoodsHouse works best). This opens up the toe box even more, however it is not necessary. The main reason I cut the stitches and laced them up differently is to straighten out the instep...this makes the instep noticeably flatter and easier to shred on. That pretty much does it as for the mods I did. The stock insole is good enough for me but you can remove that and insert your own insole (obviously) just like Lavers. That pretty much does it on my part..Im sure there are other mods but these are what I did. The best modding utencils to be used while modding these are pliars, tweezers, and a razor blade.
SHOE INFO/PERSONAL EXPERIENCE
Though I have only kicked in these shoes fully modded for a few hours, I can definitely say I prefer them over Lavers. The following is my personal opinion on the shoe. First off, I like the toe box much better for setting because it is so open and free (there isnt walls around it like Lavers). Secondly, I definitely like the instep because it also sets the bag nicely with little effort and it is almost as thin but grippier than mesh Lavers. Lastly, I really like the overall shoe quality and support. These actually feel like REAL. Solid. Shoes. They don't give that cheap feel that Lavers do. They are very comfortable and fit very nicely. The support is noticeably better for me because usually after my shred in Lavers, I have sore knees and an achy back..well after my shred in CT520s I didnt experience any of those pains, or at least not as strong.
I would definitely recommend these to anyone who is seeking stronger support and shoe quality. These make a fine footbag shoe and I will probably won't be wearing Lavers anymore.
I bought these shoes from www.NBWebExpress.com for $44.99 and the shipping was blazing fast (3 days). There is also a 30-day warranty, so if you don't like the shoe you can send them back for a full refund. Once again, Lavers are a great footbag shoe, and so are these.. I just like these better
Here are some pictures of the fully modded CT520.






Phew, these make a huge "mod mess"
Here is a small footbag video of my first real shred in these babys
