Diving fins No name Fly Pro size 39-40 — adjustable swim fins for snorkeling and scuba

No name Fly Pro size 39-40 open-heel diving fins are designed for recreational snorkeling and scuba use. The fins combine a standard foot pocket with a full-length blade to increase forward thrust while aiming to reduce leg fatigue during extended swims. Adjustable straps accommodate a range of fits and make the fins compatible with neoprene socks. Their construction suits beach use, pool training and shallow-water dives where maneuverability and comfortable propulsion are required.

Advantages

The Fly Pro fins provide efficient propulsion through a full-length blade profile that channels water with each kick. An adjustable open-heel strap ensures a secure fit over neoprene socks or bare heels and allows fast donning and removal. The standard foot pocket balances comfort and control, helping to maintain efficient kick technique during longer sessions. The design focuses on simplicity and reliability for everyday recreational diving and snorkeling.

Suitable for

• Snorkeling along reefs and shorelines
• Recreational scuba diving in shallow to moderate depths
• Pool training and swim technique practice
• Beach trips and travel where compact, adjustable fins are preferred

Key specifications

• Size: 39–40 (European sizing)
• Open-heel design with adjustable strap for varied fit and use with neoprene socks
• Standard foot pocket intended for comfort and control
• Full-length blade for improved thrust and reduced leg fatigue
• Suitable for snorkeling, recreational scuba and pool use

How to use

Before entering the water, adjust the heel strap to achieve a snug but comfortable fit over bare feet or neoprene socks. Put the foot into the pocket and tighten the strap so the fin remains secure during kicks without pinching. Use long, steady kicks from the hips with minimal knee bend to maximize propulsion and reduce fatigue. After use in salt water, rinse the fins thoroughly with fresh water and allow them to dry away from direct sunlight to preserve materials and fit.

Usage recommendations

For best results during snorkeling and recreational dives, pair these adjustable open-heel fins with thin neoprene socks for added comfort and to prevent rubbing. Use controlled, hip-driven kicks and avoid excessive rapid fluttering to conserve energy and extend bottom time.
