CAPAS snorkel fins are short, open-heel travel fins with adjustable heel straps, sold in three sizes that run from kids’ US 9 to US men’s 13. CAPAS sells them for snorkeling, pool and sea swimming and bodyboarding, and they suit a traveler who wants fins that pack small.
WaterSportHQ editors have not worn these fins. These notes cover what the CAPAS Amazon listing (B073QH1CKT) says, checked on 2026-10-21, and what it does not say.
What the CAPAS listing says
- Type: short blade, open heel, “Travel Size Short Flippers for Snorkeling Swimming”.
- Material: the materials row says plastic and rubber. A listing image says PP and TPR (polypropylene and thermoplastic rubber).
- Foot pocket: one piece, which CAPAS calls “soft” and “flexible enough for barefoot”. It also fits fin socks or dive booties.
- Straps: soft heel straps with large thumb loops and buckles. A listing image says CAPAS “provides lifetime replacement buckle straps”.
- Storage: filler pads inside the fins keep their shape in storage.
- Flex: a listing image claims “90° bending”, “neither too hard nor too soft”.
The listing gives no blade length, no fin weight and no warranty term. It does not say whether the fins float or sink. An older version of this page called them silicone, but the listing does not.
How to choose the size
The size chart in the listing images gives:
| Size | US men | US women | US kids | EU adults (kids) |
|---|---|---|---|---|
| Kids JR | 1 to 4 | 2 to 5 | 9 to 13 | 33 to 35 (26 to 32) |
| S/M | 4.5 to 8.5 | 5.5 to 9.5 | None | 36 to 41 |
| L/XL | 9 to 13 | 10 to 14 | None | 42 to 47 |
The listing contradicts itself for some women. Its size bullet says adults between 4.5 and 8.5 pick S/M and adults between 9 and 13 pick L/XL, without saying men’s or women’s sizes. By the chart, a women’s 9 is S/M; by the bullet, it is L/XL. The chart splits men’s and women’s sizes, so go by the chart.
CAPAS says to size up if you wear dive booties.
Are CAPAS fins a good option for a beginner snorkeler?
On the listing, several features suit a beginner. The open heel and buckle straps adjust, so one pair can be shared across a range of foot sizes. The foot pocket is made for bare feet or booties. The short blade packs in a carry-on.
Editors’ rule of thumb: a short blade takes less leg strength per kick than a long one, but moves less water with each kick. That suits easy snorkeling near the surface more than long swims against a current.
What these fins are not good for
- Long swims or diving: CAPAS sells them as short travel fins and gives no blade length. For a longer blade, the Seavenger Torpedo below lists 16 inches.
- Bodyboarding in strong surf: the listing names bodyboarders, but it gives no detail on how the straps hold in waves. For fins built for bodyboarding, see our bodyboard fins guide.
- Buyers who need the fin weight: the listing does not give it.

How CAPAS compares with the Seavenger Torpedo
The Seavenger Torpedo is also an open-heel fin with adjustable straps and buckles, and its foot pocket is “soft enough to wear barefoot or with booties”. The differences on the listings:
- Length: Seavenger lists the fins as 16 inches long. CAPAS gives no length.
- Extras: Seavenger includes a quick-dry mesh bag. CAPAS lists no bag.
- Sizes: Seavenger sells XS/XXS, S/M and L/XL. Its listing has no size chart that maps them to shoe sizes.
- Weight and warranty: Seavenger lists an item weight of 1.6 pounds and a 90 day warranty.
The Seavenger listing showed one left in stock on 2026-10-21.

What to check before you buy
- Your shoe size against the chart, not the bullet, and one size up for booties.
- The strap and buckle on arrival: adjust them on dry land before your first swim.
- Where you will swim: for bodyboarding, compare the fins in our bodyboard fins guide first.
