I don't pretend to be an elite, but I've found that Inov8 X-Talon 190 or 212 are far superior to road running shoes. Very versatile shoes as they are mostly used for forest O, but the grip is great on wet grass and wet paving that you frequently find in sprints if it's been raining or there'a a heavy dew.
Recently I've acquired a pair of Inov8 Parkclaw, so might try these out at my next sprint race.
