The Seavenger Torpedo swim fins are open-heel snorkeling fins with adjustable straps and quick-release buckles, sold with a mesh bag for travel. Seavenger’s chart gives three sizes, from kids 10 to men’s 13 and women’s 14, with fins 14 to 16.25 inches long. The listing does not say whether they float.
These notes cover what the Torpedo listing says, who the fins fit and what they are not built for. For fins made for bodyboarding, see our bodyboard fins guide. WaterSportHQ editors have not swum in these fins.
What the Seavenger Torpedo listing says
Checked on the Amazon listing (“Seavenger Torpedo Snorkeling Fins for Travel”) and its gallery images on 2026-10-21:
- Type: open-heel fins with adjustable straps and “easy-click” quick-release buckles.
- Foot pocket: “soft enough to wear barefoot or with booties”.
- Length: “16 inch long”, by the bullets.
- Material: plastic, by the material row; the bullets say “sturdy material that still maintains flexibility”.
- Weight: 1.6 pounds, by the item weight row.
- Use: the title says snorkeling, the bullets say swimming and training, and the sport row says scuba diving.
- In the box: the fins and a quick-dry mesh bag that Seavenger says fits a carry-on.
- Warranty: 90 days, limited.
The listing does not say whether the fins float or sink. An earlier version of this page said they sink, but no listing confirms it.

The listing disagrees with itself in two places. The bullets call the fins 16 inches long, while the chart gives 14 to 16.25 inches by size. The age row says adult, while the chart includes kids’ sizes.

What the Torpedo fins are not built for
- Bodyboarding in surf. Seavenger sells them for snorkeling, swimming and travel, and the listing does not name bodyboarding. Editors’ rule of thumb: for bodyboarding, pick fins sold for it, such as the ones in our Hydro Tech 2 notes.
- Buyers who want fins that float. The listing does not say.
- Feet between sizes. Each size covers a range of four or more shoe sizes, and the listing gives no advice for the ends of a range.
Editors’ rule of thumb: when a fin’s listing does not say it floats, plan for it to sink, and keep the straps snug.
For swim training: Speedo long blade training fins
The Speedo Swim Training Fins are a pull-on fin in natural rubber, with an open toe pocket and no strap, by the closure row. Speedo says the long blade is “ideal for new swimmers, and young team swimmers”. The listing sells sizes 3X-Small to XX-Large.
The listing gives no shoe-size chart and does not say whether the fins float. Its title says unisex adult, while the age row says youth.

Before you buy
- Your shoe size against the Torpedo chart above, and whether you will wear booties.
- Editors’ rule of thumb: try the fit on dry land on arrival, while a return is still easy.
