Q1: How do I choose the fin stiffness? Is it related to size?
Fin stiffness selection is closely related to your body weight and is generally not determined by your foot size. For scuba diving, you should also take the total weight of your diving equipment into account.
For example, divers carrying heavier equipment may require stiffer fins to ensure sufficient propulsion, while freedivers or lighter users may prefer softer fins to reduce leg fatigue and improve comfort during longer sessions.
Our recommended weight chart serves as a general guideline. However, the best stiffness ultimately depends on your personal preferences, diving style, fitness level, kicking technique, and diving environment.
To help you make a more informed decision, we provide a recommended body-weight range for each stiffness level.
Q2: How do I measure my feet and determine my size?
You can refer to our footpockets size guide and fitting reference to measure your foot length, foot width, and instep circumference.
If you are unsure how to measure correctly, feel free to contact us through our official LINE account or Instagram. We offer free sizing assistance—simply send us photos of your feet along with your measurements, and we will help determine the most suitable size for you.

Q3: Do you offer customization services?
At the moment, our customization service is available only for Chinese-speaking customers, as the process requires detailed communication throughout production. Therefore, customization is currently not available for international customers.
Q4: What is the difference between carbon fiber and fiberglass fins? Which one should I choose?
Carbon fiber fins are lightweight, highly responsive, and offer excellent energy return. They are ideal for advanced divers or users who spend extended periods in the water. Their superior efficiency helps reduce energy consumption and leg fatigue, making them a popular choice among experienced freedivers.
Fiberglass
Fiberglass fins are translucent, visually appealing, available in a wide variety of colors and designs, and offer excellent durability and flexibility.
They provide stable propulsion and excellent value for money, making them a great choice for recreational divers, casual users, and those who do not require high-performance equipment. They are also well suited for regular training.
If you are unsure which material is best for you, feel free to contact us. Based on your diving habits, experience level, and physical condition, we will be happy to provide professional recommendations.
Q5: What should I know when traveling with fins?
For long-blade fins, even the largest 32-inch suitcase may require the blades to be slightly bent in order to fit. We recommend considering travel fins for frequent travelers.
If you need to pack long fins, carefully bend them and wrap them with thick clothing such as towels, ponchos, or wetsuits to protect them from concentrated impact and potential damage during transportation.
