To (again) help with sizing
Trainers : 8
Lunar 1 : 8.5
Racers : 8 & 8.5
[reference shoe of vans authentic : 8]
I feel they all fit true to size.
Lunar 1, 8 would be better fit but .5 up is not too uncomfortably big.
Same goes for Racers but seems slight narrow by the arch of the feet compare to same size trainers.
Still I prefer TTS for racers which seems to reduce wrinkle around the tip toe area when its .5 bigger.
Hope this helps
