I like these Siren Ventilators so much, I'm going to buy a second pair.

I've been wearing a heavier-duty hiking boot (the Keen Targhee) for a couple of years, and even though the Siren Ventilator is a lighter weight shoe, the soles on these Merrells provide much better traction (ironically).

I was hiking on hardpacked and slightly iced-over snow recently, and these Merrells performed better than my Keens ever could.

And, as others have noted, these Merrell Siren Ventilators are very comfortable.

I've been a fan (not sure for how much longer) of Tifosi glasses for several years and own about 4 pairs of the Forzas. But I scratched up all my other lenses and they weren't interchangeable, so I wanted something with an interchangeable lens.

These were on sale so I tried them out and am not happy. In fact, I was so maddened by these glasses, I postponed my ride to write this review!

I've popped the lenses out and tried on 2 separate occassions to get them back in, and I cannot get them in.

Unfortunately, I missed Backcountry's 30-day return window on these and am stuck with glasses where I can't get the lenses in them.

I'll probably contact Tifosi directly and ask for an exchange/refund, but in the past when I've contacted Tifosi, their customer support hasn't been great.

They once had a $10 lens replacement plan (maybe they still do) but it's such a hassle: you have to find your receipt (yea right! the glasses are old), print a form off the internet (I have no printer), send it in, etc. I couldn't get thru the obstacle course!

And then some time passed and I contacted Tifosi again, and they said NOTHING of the lens replacement plan, just encouraged me to buy new.

So I still have the 3-4 pairs of scratched Forzas. I refuse the throw them away: they just need new lenses, not to go to a landfill.

Depending on how things to when I contact Tifosi cust service, this could be the last pair of Tifosi's I ever buy, and we'd be ending on a low note indeed.
