Kiefer Thrust Swim Fins

These fins are identical to U.S. Divers fins. I ordered both sets in the same size in order to compare them. I chose to keep the Kiefers because the U.S. Divers were a tad bit too large. They flexed with each stoke and I felt them bend in the arch of my foot. Otherwise, they are great fins. I thought I was ordering red ones but they were delivered in blue, which is fine with me. The photograph on the order page showed them in red so I don't understand the mixup, oh well. I use these fins in the swimming pool and they are great for lap swimming. They do float, not that I cared about that feature. I removed a fin on the bottom on the pool and it eventually rose to the surface. I guess that's a good feature if you cared about that. I don't plan on losing them in the pool.

When they arrived one of them looked warped in the opening for your foot and they looked like they had been used before. They are stiff and very uncomfortable to wear. I loved my speedo fins and they were out of stock so I thought I would try these, they are not worth it. I have no idea how they have such a high rating. Happily Speedo has some back in stock so I'm getting those again.

They function well-ish, but as mentioned by the previous reviewer these are NOT good quality flexible fins and if you don't have very strong ankles they probably won't work for you. Also I used the sizing chart when selecting my size but these are VERY narrow and they sort of smash your toes if you have wide feet. I ordered a new set from another brand and may return these.

These fins provide enough flexibility to allow for AWESOME thrust while still offering a decent amount of resistance. LOVE THEM! It appears they have been manufactured with BETTER MATERIALS!!!!!!

Perfect! My son has wide feet! Not super wide but too wide for most fins. We find that the Kiefer fins fit perfect! So, if your feet are on the wide-side, haha, GO Kiefer!!!

Christmas Gift for my Stepfather . He thinks they are great and fit him so well.

My daughter loves these flippers!! She wears them for swim practice and lives them! She has a wide foot and these fit her great! Would recommend and but again!!

These flippers are great. They used them at our local Y and we picked up two pairs for our kids. They work great and have proven to be quite durable.
