The Rob Allen Scorpia Evo is a long-blade freediving fin with a co-moulded foot pocket and blade. Integrated rail guides and water channels help guide the blade through the kick, with a pocket intended to be fitted with neoprene socks.

Features and benefits

The softened blade has integrated rail guides to help control sideways movement.
Water channels guide flow along the blade.
The co-moulded blade and thermo-rubber pocket form one assembly; this is not a replaceable-blade system.

The existing model guidance recommends approximately 3 mm neoprene socks. Sock thickness changes pocket fit, so try the actual socks you intend to use. Do not automatically size down or allow loose growing room.

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.
