Radbug 100, Bodyboard Fins,turquoise blue

Surprisingly good

When these arrived I was disappointed at the small size and the short blade. I honestly thought they would have too little power and thrust for proper bodyboarding. But when I tried them out I was quite surprised, compared to my Dafins brand I normally use, it might be that it's necessary to flutter kick slightly faster, but not by much if any, and I forgot that I didn't have my Dafins on. Quite a revelation for such small fins, I think their effectiveness comes from the fact that they're very well streamlined, with very little drag. Quite comfortable also. Seem a little small and snug for their size designation, but that helps with not being blown off by the waves, less loss.

Calzante estrecho

Tiene un empuje medio, bueno si no estás en forma, pero la horma en la parte distal del pie (los dedos) es muy estrecha. La cinta de sujeción del tobillo demasiado fina.

Unas aletas muy muy economicas y muy eficientes

Estas aletas en un pricipio no las anunciaria como principiantes si no para hacer drop nkee para eso las habeis echo no para aprender aletear para eso hay otras aletas que teneis que son para eso ,,,, Olas de 3 metros funcionan perfectamente asi es no hace falta decir que por lo que valen deberian tener un precio mas elevado El comp de la eletas es de alta calidad estas aletas recomiendo llevarlas de tu numero de calzado y si quieres llevar escarpines un numero mas pero siempre con escarpines de 1.5 2 mm no mas Son las aletas de propulsion cortas pero ofrecen un grip optimo en el agua El juego de comp de la aleta semirigido abajo arriba blando tiene mucho confort no las compreis anchas de vuestro numero os quedara como un guante sin rozadura tambien os recomiendo un poco de baselina o crema en el pie y luego poneosla en el agua sentireis como se aclopa al pie y no sufrireis ninguna rozadura son aletas para radicales

Gran compra.

Excelentes, super comodas y funcionales. Luego de 15 años con unas redley le he dado chance a estas y no han defraudado. Lo unico malo es que no flotan. Tampoco se hunden super rapido pero igual. Seria bueno que las proximas floten. En caso de perderlas en una ola tienes mas posibilidad de encontrarla.

Excelente relación calidad/precio

Unas aletas magnificas por lo que valen, muy cómodas y además la pala es lo suficiente corta para que sean perfectamente validas para hacer dropknee, en resumen unas buenas aletas. Lo único, si las usas con escarpín coge una talla más, calzan algo estrechas.

At radbug, we design products for 4 levels: novice, beginner, intermediate, and advanced.

- Novices: Up to the navel, no fins, small waves < 20", propulsion by pushing your feet on the ground and riding the wave to the shore. For a 1st wave-riding experience (bodyboard with grips). - Beginner: Gentle turns in waves up to 40", propulsion with fins. A must for learning to bodyboard. - Intermediate: Waves up to 5', more speed, and the beginning of tricks (360°, El Rollo, etc.). - Advanced: All types of waves, command of tricks, even aerial: ARS, 360°, tube...

These fins are designed for beginner bodyboarders and make for more comfortable propulsion.

The softer materials of the sock and the heel strap make it more comfortable. The reduced blade reduces the size, so that beginners feel more confident when entering the water and swimming in waves. The stiffer blade and side ribs allow for gentle and regular propulsion. The symmetrical shape allows a good balance between kicking power and fin size. For extra comfort, add neoprene socks.

Choose the right size of fins.

Always try on the fins before buying them. Your foot should be supported without being compressed. The back strap should be in contact with your heel and your toes should not be bent. If you add neoprene socks for comfort and/or warmth, you will need to go up half a size. Consider trying the fins on with and without socks at the time of purchase. Using or not using a fin leash will also require you to go up or down half a size.

Non-floating fins / fin leashes recommended.

For greater efficiency, the fins must remain underwater. Which is the reason why they are sufficiently heavy to avoid splashing at the water's surface, especially when used by beginners. Consequently, the use of fin leashes (available separately) is strongly recommended. Leashes make the fins more comfortable and avoid the risk of losing your fins when in the water.

Hold in the wave.

To ride down the line of the wave on a bodyboard and not swerve off to the side, you can use fins to help you. The side ribs will help you to stick to the face of the wave better and hold your line. Asymmetric fins (e.g. RIP fins) can accentuate this phenomenon and require good bodyboarding skills since, with the thrust of the fin not being symmetrical, it results in additional twisting forces in the knees. It is therefore reserved for advanced riders.

Safety and behavior rules for the water - part 1.

Bodyboarding is a fantastic sport, but one that requires everyone to respect certain basic rules to preserve the safety and enjoyment of all. 1- Ask about and observe the characteristics of the spot: current, rocks, tides, the size of the waves and the crowds, etc. 2- Don’t overestimate your level, and go for an easier spot if your skills aren’t on par with the conditions. 3- Use suitable equipment: Leash, fins, and board in good condition, suitable wetsuit.

Safety and behavior rules for the water - part 2.

4- Respect the rules of right of way on the waves: Right of way goes to the person closest to the peak. 5- Follow the direction of the wave when moving toward the peak to keep from cutting another boarder off. 6- Use fins if the water is above your hips. 7- If you’re not using fins, it’s recommended you keep to a supervised area. Lifeguards can tell you where these are. 8- Bodyboard in a group.
