cuz ive seen SEVERAL pairs with this, and ive had plenty in my possession, people wanting me to take it out, or sell them for them. its technically not ink, but the laser print clearly transfers. if it was standard ink, it wouldnt transfer, and it wouldnt fade over time. ever leave a laser printed receipt in your wallet? or exposed to sunlight? it fades like crazy and is unreadable. i use a zebra laser printer on a daily basis, im very familiar. if you dont think the "ink" can transfer, then feel free to prove us wrong by leaving a receipt under your ice sole in direct contact for a while and let us know how that works out for you, then find a solution on how to remove the transfer.
