So I want this to be easily searchable. Big Calves, Large Calves, Ski boots, thighs quads burning, forward lean, problem. So yeah that was basically the problem. Had all of the above. My calves are a beefy, 17 1/2 inches in diameter, freakishly huge. Therefore pushing me way forward, I was basically holding a squat all day. I'm 220 lbs and 5'11'', workout three times a week, hike, use the stair stepper three times a week, can keep up on a hike with people that are ten years younger, workout, and are tiny females. I'm in shape enough for a 38 year old dude. I would ski short periods of time and get the shaky, rubbery, burning legs, the kinda legs that make it easy to fall.
Anyway, here is how I did it, beat this problem. First, ignore people that tell you that you have to do squats or exercises or whatever. Yes, I do get my "ski legs" back after a while but that is minor. With 17 1/2 inch calves, strength in the legs is not my problem. Step two: I got Nordica Cruise 100 boots. they sell cruise 110 now so i would recommend those. They have a removable spoiler, and you can turn a little dial and they will open up a little bigger. Step three: sent boots to www.southernski.com . So this is gonna sound like an advertisement for this company but it isn't. So the dude that owns the place is super nice, and kinda science "y". This guy actually tilted the cuff of the boot, using the diameter of my calves, and the angles of the boot, and I swear the number for "pi" to tilt the boot cuff back,so that I could stand up straight like a regular human being with normal calves. I did all of the above and I can ski longer and am way less fatigued. I hope this helps the dude who can out air-squat any body he knows, that has huge calves that gets frustrated with people who think you are out of shape.
