Materials
Aluminum pedals or Composite pedals? Each material has its advantages and it all comes down to what you prefer.

Aluminum pedals are more premium — the best grip, the most durability and nicer aesthetic.

Composite pedals are made of high density plastic, which are a bit lighter but are also more forgiving if you slip and give yourself a shinner on your mountain bike. The composite body also deflects impacts better, great if you're riding BMX, street or dirt jumps.
