Went to double T factors this season. I'm a 9-9 1/2 and mediums are very snug, but not uncomfortable. Feel is very connected Lots of slime to get in. I was told when buying they'll feel very different and expect 5-6 sets to settle in. I don't tighten the bungees. I've found tfactors to give great support. They release very well as had some world class falls and both feet popped out, which I was glad to see. I cut the excess laces and tied knots in the excess cord as the plastic slides from D3 can come off easily. Personally I love the feel of these as they do a good job of holding my feel firmly in place, well connected, little if any movement. Forces yo to ski more with hips vs pushing with feet.
