Using runrepeat listings, your flyknit racers are 130g lighter than the speedcross. A very different trainer.
As @Sainsburys_Ed mentions they're good hikers too, I also wear mine for gardening too & also long stints on feet on a hard (painted concrete) surface at work on which road shoes quickly give me sore feet. I do run in them too still.
If you want a really light but grippy trail shoe it may be worth a look at the inov8 x-talon 212, as name suggests 212g. They'll wear out quicker on harder surfaces though if owt like my 190's (my xc shoe past 2 seasons, sadly discontinued).
Would also recommend 212s, I've got a pair that have seen me through 18 months and approaching 700 miles. Worth checking the fit though, there's a precision and a normal width fit and they are very very different.
