TUSA X-Pert Zoom Z3 Open Heel Strap Fins

Over 5 years of research and development brought the highly regarded X-Pert Zoom split fin.

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 degree Angled Blade Design and EZ strap buckle system make the SF-15 THE fin for divers.


  • Three material design for increased performance compared to standard split fins
  • Patented 27 degree 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 and buckle system

TUSA's Angled Blade Design:
When using the standard traditional blade fin, with the leg completely extended, there remains an angle of 27 degrees 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 degree 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. TUSA developed a robot that can replicate the kick-cycle and movement of a human's leg. The robot is able to mimic the motion of a human exactly and relay accurate data. TUSA has been able to analyze the performance of the fins under several conditions. The robot is able to simulate swimming through the water using kick variations, such as a large scissor kick with a slow repetition and vice versa. Using the latest technology, this robot measures the energy expended during the kick and the propulsive force that is created using that energy. 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.

Question asked
on 2/17/2011
I am interested in purchasing the Tusa Xpert Zoom (SF-15) open heel fin and wanted to confirm my fin size. My boot size is a 8-9 mens therefore the Medium looks like the proper size, right? Also, does your free shipping offer apply to Hawaii customers?
Answer by Bill

Hi There, Yes you are a medium: Medium 27 1/4 in. Mens shoe size 7-11. We do not offer free shipping to Hawaii but we do offer USPS Priority Mail or if you are not in a huge rush we can offer Parcel Post which take a bit longer.

Hello, I would look at the oceanic v6 open heel fins as these may not be able to accommodate as I know they go up to size 13.

Hi, can these fins be used without boots for snorkeling?
Answer by Bill
on 8/26/2013
These fins are made to be worn with boots or at the very least a sock. I would not wear them without some sort of boot or sock as blisters can be an issue.

These fins look great, but probably over-kill. I used to snorkel, but now due to peripheral neuropathy I just need leg exercise in the pool and kick board. My 25 year old fins have torn and they hurt my toes. My shoe size is 11.5 extra wide. What fin would you recommend and what sock so that I don't get blisters on my toes. Thanks very much, George

Hi George, there are a few different fins that should work. The Cressi Palau fin (SKU: CRECA13), the IST Speedy Open Heel fin (SKU: 5575J), and a few others. If you are trying not to get blisters on your toes, you should get a 2 or 3mm sock. There is the Scuba Max 3mm low cut sock (SKU:SCUSO302). Please let us know if you have any further questions. Have a great day! Sincerely, Jamie, Customer Service
