I can’t say that I’ve ever tried running barefoot on ice, so I may be entirely of base with this statement: I think this record is pretty soft:

The fastest time to run 100 m (328 ft) barefoot on ice is 17.35 sec set by Nico Surings (Netherlands) at the Ijssportcentrum in Eindhoven, Netherlands, on December 8, 2006.

High school boys can go sub-11 seconds wearing spikes on a track. Does taking away the shoes and throwing in some ice justify the 6+ second difference?
