Heres my method on how to keep soles icey.
Ive had my bred 6s for about a year and 4 months now and they are still icey.
Copped them 2 months after initial release.
Materials: Sponge and heatable container of water
1. Heat up the bowl of water..for like 4-5 minutes until its real hot
2. Scrub your icey sole...removing all dirt throughout the soles. Also scrubbing the soles so
the embedded dirt can escape.
3. Then finally once you feel you have done step 2 completely and correctly. Dry them off Thoroughly.
Drying them off is the most important step. Failure to do that completely makes them yellow even more.
If you follow these steps after every wear, your soles should stay icey for as long as you want them to.
It really only works when you just got them or they're still icey. If the soles are already super yellowed..method wont help much. After seaglow if wanted, start the method up.
I have provided pictures of my soles to show to that it actually works:
