Finswimming Monofins: what actually changes the decision
Finswimming Monofins is the Finswimming equipment category where cmas homologation, monofin-versus-bi-fin event, blade stiffness create the biggest buying differences. The products and guides below separate those decisions instead of treating every option as interchangeable. Finswimming is a speed discipline using monofins or bi-fins on the surface, underwater or in open water. CMAS currently lists 2026 World Cup rules plus homologated bi-fin, monofin and swimsuit appendices, so competition buyers must verify model approval rather than assuming any fast fin or racing suit is legal.
