Most foot soldiers would wear chain armor with pieces of plate here and there, and thats only the extremely rich who could afford things like that.

Mail was much too expensive to produce to outfit "Most foot soldiers" with. For much of the middle ages, most foot soldiers wore some kind of Gambeson and a helmet. A mail hauberk was the next step up, as it was still cheaper than a full mail shirt.

Plate cuirasses became common among the more wealthy in the late middle ages. By the early modern period, when the Almain Rivet (half-armour) became cheap enough, you'd see smaller professional armies be outfitted with them. But the common peasantry generally couldn't afford either for the longest time.

Its funny when people talk about full plate being 'practical' and 'realistic' when it was mostly a sign of status, ornamental and incredibly impractical.

As a rule, if something didn't work in war, people wisened up and stopped doing it. They weren't stupid, just because they didn't have the same wealth of knowledge thay we do.

Knights didn't want to impress and get killed, they wanted to win and live. No amount of status will help you if your opponents dance on your grave. If plate was as much of a liability as you claim, it wouldn't have become more popular, comprehensive and accordingly expensive over time, until Gunpowder started accelerating weapons development far beyond anything protection could keep up with.

You're right that full plate was often worn by heavy cavalry, both as a matter of wealth and as a matter of utility. Heavy Cavalry were shock troops, morale breakers, designed to make your (often not professionally trained) soldiers falter, break order, open gaps in their ranks to get out of the way of the thundering beast charging at them. The appearance added to the indimidation, but it also helped protect on the way to and through the infantry lines.

There were mounted heavy infantry too that would ride to battle, then dismount and advance with the soldiery, and there too did plate help protect. It's easier to confidently walk into a line of levied peasants pointing spears at you if you're hard to actually wound.

In either case they were made of much thinner plate than some pop culture depictions would make them out to be - about 20-30kg. A modern soldier's kit isn't lighter than that.

many battles by extremely well geared soldiers were lost because they couldnt out maneuver barely armored militia, or even just rain.

Most battles that saw heavy cavalry lose were because of miscalculations, not because the armour made them immobile. If infantry in good order maintained cohesion, but the cavalry kept charging instead of turning to feint, they likely got stuck in a melee where numbers would be against them. If they rode into heavy missile fire, no amount of mobility will magically let them dodge the arrows, but a good plate would increase your chances of survival. If they got stuck in the mud as sitting ducks, that was because horses don't always deal well with running across uneven ground, particularly with sudden pitfalls where the ground is softer, and even more if heavy rain and blinders impeded their vision.

Yes, bodkin arrows from a sufficiently powerful warbow at sufficiently short ranges and steep angles of impact may well penetrate plate, particularly the less solid visors, and arrows in general bear a risk of felling your horse, but some armour is better than no armour.

Like I said, if it didn't help in battle, they wouldn't go to such lengths and expenses to produce it and wear it to battle. They'd wear it to ceremonies, to parades and to tourneys, but not to war.

I'll leave you with this demonstration of mobility

This is a common misconception but it's just not true. As you can see in this video mobility is hardly a problem. It certainly would be possible that a piece could be bent or damaged badly enough to hinder you, but a properly fit set is going to let you do whatever you need to do in a battle. You are certainly right that it was expensive though, full plate was similar to buying a luxury car. It was rare but not that rare, a sign of wealth and social class but not like only kings could wear it. And it certainly was not strictly ornamental.

There is only once context of actual use where this is true: jousting. And this is because it was a sport that the competitors expected to walk away from.

Apart from that, what you said is a complete myth. Mobility what highly important on the battlefield, and armorers had to keep that in mind throughout the middle ages. There are many instances where troops acquire or are given pieces of armor that they later discard because it was too heavy or hindered them, and the weight you're imagining is not all that great. And this is not a problem unique to the middle ages - it still happens up to the modern day

As for full plate, it's not actually as heavy as you think it is because there are a lot of shaping techniques used to gain the maximum amount of strength for the least amount of weight. Generally Late Medieval full plate harness weighed 35-55lb Source

There are medieval reenactment groups such as the Society of Creative Anachronism (SCA) or Historical Medieval Battle (HMB) where people will regularly wear armor and fight. I myself do this, and my kit fluctuates between 40-55lb depending on what I'm fighting with that day. Adding that to my body weight results in a total of about 200lb, and dare you to claim that people at that weight can't move around.

What's even funnier is that groups like HMB tend to have armor that's significantly heavier than the medieval period because they need their armor to last a lot longer. In period, men at arms only needed their armor to last a few battles, while reenactors look to use their armor on a weekly-to-monthly basis for years

I saw a video of a guy doing breaststroke in full plate mail once. Sure, it was rough for him, and he was already pretty fucking good at swimming, but he didn't sink like metal Mario or anything like that.

Almost completely wrong
