Why does this piece of code give me an error?

[Laslod]

So I'm currently learning about foreach loops, enums and lists. Now, I have a class called Shoe and an enum called Color:

class Shoe
    {
        public Shoe(Color color, int age)
        {
            this.color = color; this.age = age;
        }
        public Color color;
        public int age;
        public string GetDescription()
        {
            return "This shoe is " + color + " and is " + age + " years old.";
        }
    }
    enum Color
    {
        Black,
        Red,
        White,
        Yellow,
        Blue,
    }

I Also have a class called LaceShoe that inherits from Shoe:

sealed class LaceShoe : Shoe
    {
         public LaceShoe(Color color, int age)
             : base(color, age)
         {

         }
    }

Ok , so here is the test i'm trying to do.

List<Shoe> shoesList2 = new List<Shoe>();
            shoesList2.Add(new LaceShoe(Color.Yellow, 20));
            shoesList2.Add(new Shoe(Color.Blue, 10));
            shoesList2.Add(new LaceShoe(Color.Red, 40));
            shoesList2.Add(new Shoe(Color.White, 80));
            shoesList2.Add(new Shoe(Color.Blue, 30));
            Shoe[] shoesarray = new Shoe[shoesList2.Count];
            int y = 0;
            foreach (Shoe shoe in shoesList2)
            {
                shoesarray[y] = shoe;
                y++;
            }
            
            int b = 0;
            foreach (LaceShoe shoe in shoesarray)
            {
                b++;
                Console.WriteLine("This shoes array has " + " lace shoes");
            }

But this doesn't work. It says unable to cast object of type shoe to type lace shoe. I'm not sure why it gives me that. I made a new list of type shoe and added 3 shoe objects and 2 LaceShoe objects to it. Then I went through all the shoes in the shoe list and populated the shoesarray with the shoes in the shoelist.

Then , All I want to do next is look for the LaceShoes in the shoesarray. Since the shoesarray got populated with all the shoe objects in the shoelist, shouldn't it also have the 2 shoelace objects of shoelist? And then, shouldn't I be able to get the amount of LaceShoes in my shoesarray? Which is 2?

Now keep in mind, I know how to fix this; All i have to do is do this instead:

foreach (Shoe shoe in shoesarray)
            {
                if (shoe is LaceShoe)
                {
                    b++;
                    Console.WriteLine("This shoes array has " + b + " lace shoes");
                }
            }

All I want to know is WHY it gave me the error. Is it because my shoesarray is type Shoe and when I use foreach loops I can only do it of the type my collection is? But if that's the case, since LaceShoe is also a shoe, shouldn't I be able to check for Laceshoes is the foreach loop?
