"a" compound
-sorry I'm a grammarian

White loops as in the shoes that give +28 speed that look purple?

I made 2 a few weeks ago, used one for a compound that failed...and inserted a nimbus spar in the other one. I used rainy doll+feather boots for that compound ,and I haven't failed with level 6 superior alchemy. If you want to know some compounds here is a link: http://wlodb.com/items/2445

Good luck compounding, it's alot of trial and error and you'd need to spend some money first to get it, so if you do not think you can successfully create white loops, it would be best to ask a known compounder or perhaps a friend to compound it for you.
