Changing the direction you point your toes while doing calf raises changes which part of your calf muscle gets the most work. Pointing your toes out targets the inner calf, while pointing them in targets the outer calf.

Turning your feet outward while doing calf raises actually works the inner part of your calf muscle more than keeping your feet straight or turned in. This means if you want to specifically build up the inside of your calves, adjusting your foot angle during exercises could help.

Changing the direction your toes point while doing a calf exercise changes how much different parts of your calf tendon stretch. Pointing your toes outward stretches the inner part of the tendon more, while pointing them inward stretches the outer part more.

How you point your feet when pushing off the ground changes how your calf muscles work together and affects how your Achilles tendon stretches. This shows that your foot angle directly influences the connection between your muscles and tendons.

Turning your feet inward while doing calf raises targets the outer part of your calf muscle more than keeping them straight or turned out. This means you can use this specific foot position to deliberately work one side of your calf if you want to build it unevenly.

When you point your toes quickly with your knee straight, your outer calf muscles work harder while the deeper calf muscle works less. This means faster toe-pointing movements naturally target the outer calf muscles more than the deeper ones.
