What size TUSA fin should I purchase in the SP 15 Xpert Zoom Z3 model? I have a 7.5 M foot. Should I purchase the small or medium size? I dive in Florida with a EVO 5mm bootie, size 6. My TUSA liberator 10 is a small. Thank you, Nancy

I wear a size 10 1/2 shoe. What size fin should I order and what size spring strap? Should I order a little big or a little small?
I would like a recommendation for a boot with this fin. I wear a 7.5 ladies shoe size, have a high arch, am planning to use mostly in warm water and would like a sturdy enough sole for some rocky surfaces. Thanks
My dad wears a 10 1/2 shoe, and I see you recommended getting the 11-13 size for this fin. Would you still recommend that sizing if I am getting him a size 9 in the Mares 5mm dive boot? I also noticed you recommended a medium spring strap for the large fin, but the spring strap is automatically added and I cant change the size. Is there a place to write a message when I place the order?
hello i have arthritis in my right ankle and am a new diver wondering if this is the fin for me. what do you think? i wear a womens 10 shoe should i order the mens 7-10 in the tusa if i decide to purchase? these fins look like they might be the right choice for a beginner...what do you advise? thanks! toni
SF-15 - TUSA Z3 X-Pert Zoom Adjustable Strap Dive FIns
Over 5 years of research and development brought the highly regarded and best-selling SF-8 X-Pert Zoom split fin to market in 2003. TUSA redefines the fin market again with the introduction of the SF-15 X-Pert Zoom Z3.
The SF-15 further improves upon the performance, features and design of the SF-8 with the incorporation of 3 materials, 10% longer blade length, enhanced propeller-fin technology, reinforced blade rails and optimized blade scoops. These new features along with TUSA's patented 27° Angled Blade Design and EZ strap buckle system make the SF-15 THE fin for divers.
TUSA's Angled Blade Design:
When using the standard traditional blade fin, with the leg completely extended, there remains an angle of 27° between the heel and the foot and the calf of the leg, causing a 10% loss of propulsion. Because the fin is angled below the body, during the kick phase, the body is pushed forward and down, instead of straight ahead. With the SF-15 fin, that 27° angle has been designed into the fin. This means that 100% of the energy expended during the kick phase is directed toward the propulsion of the diver. To achieve maximum performance from this fin, use a small bent-knee kick with a light rhythm. This creates less strain on the leg muscles compared with traditional fins, reducing the diver's fatigue and subsequent air consumption.
> Three material design for increased performance compared to standard split fins
> Patented 27° Angled Blade Design
> Enhanced propeller-fin technology optimizes efficiency
> Multi-compound foot pocket increases power transfer to the fin blade
> Reinforced side-rails decrease blade separation increasing stability and kick-style versatility
> Optimized blade scoops increase water channeling
> Innovative hydrofoil design that produces forward motion (propulsion) with less effort
> 10% longer blade than SF-8 for enhanced propeller effect
> TUSA patented EZ Strap and buckle system
> Color: Black (BK), Cobalt Blue (CBL), Flash Yellow (FY), Metallic Red (MDR), Pearlescent Pink (PP), White (WH)
> Sizes: S, M, L (PP available in S, M only)
TUSA’s advanced split fins employ Propeller-FinTM Technology, which delivers ultra-high performance with a low amplitude rapid flutter kick. As the fin moves through the water its two wing-shaped surfaces create lift and forward propulsion like a propeller. Any water traveling over the top of the blade is funneled into and out of the split between the blades. Efficiency is increased while drag and effort is reduced.
EZ Strap and Buckle System
TUSA's EZ strap and Buckle System allows fins to be quickly and easily adjusted with minimal effort. Adjustment can be made while the fins are worn, allowing for a precise fit and ease of removal when necessary.
Angled Blade Design (A.B.D.)
A standard flat fin inhibits propulsion solely by fault of design. An angle between the heel of the foot and the calf of the leg remains when the leg is extended to kick. This angle causes approximately 10% of the propulsion to be lost. The Angled Blade Design accommodates for this anatomical characteristic and ensures maximum efficiency throughout the kicking cycle.
