i haven't noticed! shit, i better check that out. i wore them out the first night I got them and went dancing and drinking...so any bleeding that might have occurred i failed to notice. i'm going to start putting some hard wears into them because they are INSANELY comfortable. i accidentally wore them with a boo overdye and didn't realize how low cut they were until then.....really, really worth the price. i dig the fuck outta em.
