Why? Our warehouse is chaos-organized. The same sizes/colors are not placed in the same location. We save money in our handling when we only have to pick from one location - that's why the quantity discount only applies to the same size and color. Consider it a bonus that we share the savings with you.

Only applies to the same size and color

These DX 3.0 fins with heel adjustment from Beco are professional fins designed to let you glide through the water as quickly as possible. The ability to adjust the heel ensures that these swimming fins fit as comfortably as possible on your foot.

These fins are for adults who want to move through the water as quickly as possible. These grey and black fins are designed with holes and shapes that glide best through the water. Around the foot, the fin is made of soft rubber, so it sits comfortably on the foot. The rest of the fin is made of a harder material, allowing you to create a lot of propulsion.

What you can use these DX 3.0 fins for

What you can use these high-quality fins from Beco for includes professional swimming training. By wearing these, you can focus on other aspects of your technique, as you don't have to worry about creating propulsion in the water.
