why do you have to have your skis as close together as possible? If it were 1994 and you were on straight skinny skis with no sidecut, maybe. Go with an athletic stance, knees bent, legs about shoulder width apart or slightly less. Yeah. you can ski with your legs together in a straight line or just cruising for "style" I guess, but if you're on real terrain or even steep groomers, you need to be in a dynamic position.
To OP, to feel forward pressure, try skiing with your knees slightly bent and at least even with your toes if you drew a vertical line between knees and toes and while your skiing, lift your toes upwards. It sounds weird, but try it. By doing that, it'll flex your ankles, and push your shins into the front of the boot. Do this throughout the day occasionally as a reminder. Even sitting at your comp with no boots on stand up, bend your knees slightly, shoulder width apart, and lift your toes as hard as you can. You will lean forward or even fall. It's just a little muscle memory "feel" tip I picked up that helped me a lot.
Forward pressure is a AHA!! lightbulb moment. I skied for years recreationally and growing up and because my skis were glued together making "parallel" turns and I skied fast and never fell, I thought I was a really good skier. However, like sooooooo many people at that intermediate plateau, I was back seat, and didn't know it. Steep bumps or difficult terrain lets you know real fast whether you have forward pressure in your boots or not.
Honestly, percentage wise, so few people on any given day at any given mountain ski with forward pressure that as soon as I see someone balanced and forward in their boots, they stick out like a sore thumb. Chances are if you see someone that sort of looks like they're eating up the terrain, and accelerating out of turns, and their upper body is quiet, they're driving their skis and you should emulate what you see. It helps with popping and absorbing terrain an enormous amount.
