I love my training fins, they're well made, super comfortable and make a huge difference to my swimming. They're my second pair, though - because the sizing of the fins is completely wrong! I am a size 42 or maybe 43, but it was a size 46 that fitted. (So my wife has gained an unexpected present - the Finis fins that don't fit me!) "Beware the Finis size-guide".

Light and comfortable, very happy with the fit.

Good quality product

Perfect fit and very comfortable.

Poor quality

They fitted perfectly after consultation with Madysin. They arrrived in a couple of days after ordering.

Can finally keep up with the rest of the squad ;)

Unfortunately the fins are too narrow for wide 2E feet. Comfort is not what you would expect when compared to an all rubber fin of old, eg.Voit. Some thought needs to be given to this, given that a good many of your buyers grew up running around barefooted, then spending hours bodysurfing in relative comfort.

I am a size 37 but these fins are a 35
its says 35-37 but not big enough for a 37 size foot I have returned for a refund

Very disappointed. Sizing way too small please fix size guide as incorrect.

The fins were too small your sizing is not correct. I take a 40 shoe which is a bit long on my foot.
Then it cost me freight to return for the next size up. Not very happy as they are a costly pair of fins. So please sort out your sizing please.

Fantastic training tool really get your feet up in correct position love them. 🩷

Sizing seems to be on small side. Too much hassle to swap for more comfortable larger size. A downfall of online purchases

Sizes are for children I think. 🤔 xxxl was about an xl. Totally wrong

Excellent product. Far better quality, lighter and faster than the Speedo flippers, plus these float! Great service also.

the size I ordered seemed a little small for the size depicted.

My 10 year old says he likes the feeling of the flippers and also the colour and they make him go super fast in the water.

Love the new fins. Very comfy and snug fit.

They’re not joking about sizing up! My son is a 36 in Birkenstocks & 4 in Nikes- he is bang in the middle of the adult Small size (euro35-37 & US3-5). There was no way he was getting his foot in the fin! Have to go shopping again, but happy to as FINIS is such good quality stuff!

Sizing description needs to be more detailed.
Fins too small, had to return

I love my floating fins. I have tried all different brands but Finis is the one for me. The staff are really helpful and efficient - I have always had terrific service.

I love my Finis fins. They are perfect for my particular needs. I needed to get a new pair urgently and they were delivered in less than 48 hours. Impressive!

I bought a pair of size L Long Floating Fins 39/42. All the shoes I wear are size 40, but the fins are very tight, and I really struggle to get them in, and they make my toes cramp easily after a few laps of the pool.

I love them however this is the second pair within twelve months. They tore at the back!

It's a good-looking, well-made product, but the sizing is closer to 42 than 44, making it difficult for me to get on. Once on, they are great but break the skin at the bottom of my big toes, so I must stop wearing them because of the chafing pain.

Great fins, a bit tight fitting initially, that was expected but even after the first day they were good.
A great product.

love these fins.

This is my 3rd pair. I always return to these. They are light and soft and comfortable.

Quick service, correct order.

Quick service, correct order.

Followed your sizing chart online. Purchased the recommended XL. Received the fins in good time. Found them too narrow for my size 9US feet. Am unable to squeeze my feet fully in them. Have not used them. Too expensive to return.

I am an in between size and found what I bought was WAY too small despite my having followed your size guide.

Can’t go wrong. Have had these before and lasted for years . Used in both pool and ocean. The fit is 100%, no bits digging into you. Worth the money for sure .
