Yeah, fins fit a bit small. I wear a size 13-14 (which is the size range molded on the bottom of the fins by the way) but anyone needing anything bigger than a size 12 should proceed cautiously. I did a bit of modification to my fins so they fit much better now than pre-modification but you may not desire to alter them. Other than that they work awesome! Good luck out there swimmers!

These things are heavy, but they do give you legs a workout. They make my old red zoomers seem light as a feather.

Only concern was that the packaging of the product was a little excessive. The product was in perfect condition though, just what I expected and true to size. Great prize too, compared to other sites I saw!

Swim with them six days per week after daily workout. They are great for building strength and stamina. I would not hesitate to recommend this product.

These are great feeling fins although I believe they fit a bit small.  Not horribly uncomfortable however.  

The fins work extremely well in the pool and I can really feel it in the quads/thighs.  

I''ve also travelled with these to the Caribbean and used them for snorkelling.  Small pack size, lighter and still propel you enough to enjoy your swim

I use these for indoor lap swimming and I felt that they''d help with my kick.  What they did was about double the effect of the work out.  Very impressed, I was exhausted after my usual distance.  It''s the boost I was looking for.
