As a swimming old timer, I guess I'll have to get used to Speedo's continual evolution.  Great, great goggles but they have so many changes (such as interchangable nose pieces, a different strap piece), it takes some getting used to.  The 1st pair I bought I broke the 1st time I tried to swap out the nose piece, so beware!  They are ultra low profile but my vision, underwater, was weird (not above water, however)...also, don't let the anti-fog fool you- They fog up just like any other goggle.

I have tried many of the speedo googles, this is one of the best.  It will fog alittle, sometimes, but one of the sprays should take care of that.  Once adjusted it is comfortable for long swims.

These goggles are great for training and races. I've used them in the pool and in triathlons. Excellent and no leaks.

Doesn't leak and doesn't create pressure headaches on those longer sets.  Worth the expense.

I've had good luck with this goggle style.  I can always depend on them to not leak.  The adjustable nose piece is a hassle to switch out .  I thought I was going to break the thing!  But is really helps to customize the fit.

Great Product ... Fits Great!
