These fins are very comfortable,they fit so well. the problem is they split at the toe at about 5-6 months of daily use. I have had four pairs split at the same time. Very expensive for only six months of use

My first pair at least didn’t rip for several years.  My second pair ripped within a year of very limited use.  Both at the side of toe box.  Women’s size 9. Good fit….Im guessing poor quality control, as I see many other reviews (Amazon, etc) with same complaint. Too bad the complaints are not stimulating some actions on the manufacturing level or product design engineering.  

The fins are very comfortable but the quality is very questionable. They rip apart from the toe too easily and they won't even last a semester. I took care of them daily, cleaning them with clear water after use in the pool but this wasn't enough to keep them longer. Stay away from these and look at other brands who have more durable equipment

I swim 5 times a week ... I love these fins but my first Switchblade were too tight, I am a size 10 so I chose size M, on the toes part, its stats to hurt so I brought A second. pair, now size L .. but they are too loose. So I think I would buy a third pair ... again size M, cause I love them so much to buy another type of fins.

Great price, great product
