Custom-shaped buttons can add a unique touch to your design while emphasizing function. Take an arrow-shaped "Next" button, for instance—it intuitively guides users forward. However, tread carefully.

The unconventional shape should amplify its purpose, not obscure it. Utilize visual cues like color contrast, subtle shadows, or size adjustments to ensure users instantly recognize it as an actionable element. Balance creativity with usability to make navigation a breeze for users, reducing any guesswork or friction.
