Cressi Origin LD Open Heel Fins Size Chart
Open-heel scuba fin sizing: Dive boots must be worn with these fins for a secure, comfortable fit. Boots help protect your feet from sharp rocks and rough surfaces during shore entries and exits, and make it convenient to walk to the water before putting your fins on. Choose your fin size to accommodate the boots you’ll be wearing.
Extra comfort with Lycra socks: We recommend wearing thin Lycra fin socks inside your dive boots to help reduce rubbing and blisters. They also make boots easier to put on and take off, reducing strain from pulling on the neoprene and seams. Lycra socks can help your feet slide into your wetsuit more easily, making gearing up more comfortable.
Fit note: These are fin and inner-pocket dimensions, not a bare-foot length chart. Cressi does not give EU/US shoe conversions in this new chart. Check the pocket with the dive boots you intend to wear.
Reading the Cressi diagram: A, B, C and D are product dimensions, not bare-foot length recommendations. Use the metric dimensions where the printed inch figures differ. Choose your size from the size conversion table above.

To measure your feet, place paper against a wall, stand with your heel gently against the wall and mark your longest toe. Measure from the wall to the mark in centimetres. Repeat for the other foot and use the longer measurement. Where a model has no foot-length chart, contact us with that measurement and your usual shoe size rather than using another fin model’s chart.
Size charts are a guide only; individual fit varies with foot shape. Check both feet and try the fins with any socks you intend to use. The pocket should hold the foot securely without curled toes, pinching or excessive movement. If you are between sizes, ask our Hallam team for fitting help.
Care and storage
Rinse in fresh water after use and remove sand from the foot pockets and adjustments. Dry in the shade before storing away from heat and direct sunlight. Store blades flat without bending them or placing heavy items on top. Check straps and buckles before your next swim.
