Board feel is fine with the KSLs once they break in. And not spongy at all like the bruins. As for eyelets, mine stayed in (unlike my GT Blazers where I popped one second wear while lacing up during a session); that's just hit or miss QC.
They KSL eyestays will start to come loose (stiches pop) *just from lacing* this happened on both shoes, on the outside, and I don't have a mad switch game), Crazy Glue required prior to wearing....
They're a very no-nonsense cupsole...I only switched off them for the 808 (fail) and would have nabbed the blk gum if I haven't been itching for mid.
RE: 808 - I keep wearing them as my hit the store, take out the trash errand shoes...and they still make every other shoe I own, skate or otherwise, like flimsy pieces of shit...the 808 is such a beast of a sneaker...I might dip on a 10.5 and return if it's a hot mess.
