I do not own nor have tried on KomodoSport LS, but you can see what I do own in my signature.
The best advice if you are unsure is go ahead and order your next size up (if you can't try them on in person), and just wear them (compare) around indoors until you decide which size you are most comfortable in.
I have some marks on the ends of my toes when I wear my tighter VFF styles (jaya LR and kso trek fit like a glove), but they don't cause any pain or discomfort even wearing them for long periods and I do enjoy the snug feeling. I have a little extra toe space in my Bikila LS and on my KSO treks I feel like the toe pockets are definitely shorter.
It's all going to depend on your foot and the style of VFFs. It would definitely be best if you could go somewhere to try them on in person, try different sizes and styles. But if you can't then you may have to to some trial and error getting them sent to you/returning. As long as you are buying from places with free shipping it shouldn't be too much of a pain in the butt. IMO, they are worth it.
Hope I could be of some help.... (FYI.. I originally wrote this post after overlooking that you had the style you were asking about in the header
and then went back and tried to fix it so I didn't sound totally off, but you get the idea)
