Not always. It depends on whether safety equipment is essential at the place of work.
You answered you own question...if they're steel toe, it will say so on the tongue of the boot.
Steel toe capped shoes don't always have steel at the cap, but it's always durable metal. This is essential as the shoes need to be hard wearing for work.
A steel-toe boot is a durable boot or shoe that has an protective substance in the toe, usually combined with a sole plate, which protects the foot from falling objects and punctures from below.
A steel toe shoe or boot has a piece of steel inside the tip (about 2 1/2 inches) to protect the toes from being crushed if a heavy object falls on the foot.
These are a very durable type of boot in which the toe area is reinforced with either a steel place or composite materials.

A composite toes shoe or boot is one in which a shield is provided in the front to protect the toes from crushing is a heavy weight falls on them. That shield is incorporated into the shoe or boot toe and is made of a "composite" material like Kevlar, carbon fiber, or plastic.
Stee-toe work shoe or work boots are often found in uniform supply stores or may be purchased on line if the desired size is known. Large shoe stores also often have a boot section.
this depends on the boot itself, a small lightweight ankle boot like a dealer boot with no steel mid-sole will weigh under 2 kilograms while a larger, steel mid-sole rigger boot made of leather with fur lining may weigh a little over 2kg. If your looking for the lightest steel toe footwear you can find, you might consider buying steel toe cap trainers. These are becoming more popular and I see many people wearing them on building sites now in the summer.
A steel toed boot (or shoe) is used to provide some level of protection for the toes in situations where heavy objects might fall onto them. Many of them are no longer made with steel, but with a strong plastic instead. So they are usually called safety-toe boots (or shoes) these days.
i think you will find, the toe goes inside the boot
No. A steel shank is a piece of metal along the sole of the boot which provides support for your foot. The Steel toe of course is a shell around the front of your foot protecting from dropped hammers or anything along that line.
