Of or relating to the demise of a dot-com company.
The dot.com part of the picture has become clear to me only recently. While I used to find the child emperors repugnant, I now find them irrelevant. I admit, I used to feel righteous when a dot.com went sneakers-up, but now I feel empathy for the hardworking folks who have lost their jobs.

There is little hope for the vast majority of the dot-com companies that were funded over the last four to five years.
More than 200 dot-coms have already gone sneakers-up. My guess is that it will be a small multiple of that this year.

Sneakers-up is a play on the idiom belly-up, "of or relating to a failed or bankrupt company." Replacing "belly" with "sneakers" is a reference to the relative youth of the entreprenerds who launched many of the newly-dead dot-coms.
This phrase also affords me the opportunity to unload all the words and phrases related to the ongoing dot-com slaughter that I've gathered over the past few months:
dotcom-uppance (or dotcomuppance)
