Product Overview

Hydroventure 2 is an exciting update to the award-winning original. Our women's waterproof trail running shoes feature our proprietary single-layer eVent® breathable/waterproof upper, a fully gusseted tongue, forefoot rock plate, 2-density injected EVA midsole, and new Vibram® Megagrip outsole. A 3mm drop, 25mm x 22mm platform means the Hydroventure 2 allows for natural movement while still offering the protection you need on wet, technical trails. The 2-density injected EVA midsole is softer near the foot but more responsive on the bottom. A new Vibram® Megagrip outsole features deeper, more generously spaced lugs for ”toothier” traction in wet, muddy conditions. Our Hydroventure 2 women's waterproof trail running shoes now have a gaiter attachment for the Topo gaiter (sold separately) and 2 lace colors for multiple looks.

Dry Feet! - tested in the Pacific NW


I have worn the Hydroventure 2 exclusively to run 60K/week on singletrack trails in the Pacific NW for the past 5 months (purchased 10/2019). The trails are very wet, soggy, muddy and even snowy yet my feet are dry. I wear gators that cover the upper laces and ankle area otherwise, splash and water from plants along the trails will get in the top. They are warmer than non-waterproof shoes so my feet sweat a bit but I don't mind because I can enjoy the trials in any conditions and still have dry feet. The grip is great on slick rocks and slippery roots, but also good in dry conditions. I wish the midfoot lacing was better for my foot but other than that these are great waterproof shoes. I wear 1/2 larger in the Hydroventure 2 than my other Topo shoes.

Happy Warm Safe Winter Running!!


Before I found Topo's at Marathon Sports I was stuck with the Brooks Gortex Ghost for winter running. It was too much shoe and a 12mm drop. I returned the latest pair (my 4th year in them) after a week and begged for a lighter-waterproof-lower-drop shoe. The Hydroventure was the answer. I bought the grey in 11 (usually a 10.5) I'll be snagging another pair.
I'm running on icey slushy trails and roads in New England this winter. The Hydroventure shoe has kept my outdoor running program together and this is not only good for race training but more importantly, my mental health. Just today I ran on the local trail that had ice, snow, and ice water puddles. The Vibram soles took it.
The protection from the elements matter for me more than most - my long skinny toes are subceptible to cold (frostbite) so I wear the thickest wool five-toe Injinji socks with the Hydroventure shoes. It's heaven in these shoes! Like barefoot running in snow....

Not Waterproof


Fits well, no rubbing on toes, plenty of room in toe box with out being sloppy or slippery.
Excellent gripe on wet grass up and down hills or even on wet side walks/asphalt.
Great shoe but it is NOT waterproof! Hiking through short or tall grass, salal and sword ferns in the PNW damp with rain, goes right through the shoe box fabric. Trail Walking in rain after a few miles, yields wet socks and squishy in soles. But they do dry out quickly when removed.
Please make a truly waterproof shoe, gaiter and I’ll be more than happy to buy it. Or test it for you!

not quite


I really like the fit of these shoes, the generous toe box makes my feet happy. They were comfortable the moment I put them on. My only disappointment, contrary to other reviews, is that they are most assuredly not waterproof. They resisted water, but after a relatively short hike on a slightly overgrown trail, brushed by salal and Oregon grape, my feet were damp. Not sodden, but it wasn't even raining. I'll wear them for the comfort and wonderful soles, but not for dryness.



I love these shoes. I have some knee problems and the relatively flat rise is extremely comfortable. The sole grips well and my feet have remained dry. Definitely order a half size larger than you usually wear.

Comfy. Size up.


I love this shoe and highly recommend it. The wide toe box is exceptionally comfy and the support and cushion is spot on, for trail running. It's not enough for the road, but it's also not meant for the road.

It's very waterproof and I think the breathability is good, but I do live in a dryer climate. So, I will test it up in Vancouver BC, in a few weeks and have a better grasp on that.
The only issue for me is the sizing. I'm am normally a size 9.0 and got a 9.5 in this style. The 9.0 does fit me in other Topo styles, just not this one. And, my right foot is just a tad bigger, so the 9.5 isn't quite perfect for that foot.

So, I do recommend going up at least 1/2 a size.

Great shoe, small problem with rubs on top of toes


I was really surprised how much I like these shoes. I normally would not order shoes online without trying them on first because I often have a hard time getting shoes that fit right. These fit great. And it was well worth the extra few dollars to get the waterproof trail shoes, because after 8 miles on trails in the rain, my feet were still dry. Only small problem is because what I suspect is the wider toe area and material to make it waterproof is I started to get rubs on the top knuckle area of my toes where the fabric folds when I move. Hopefully this can be managed with being careful with what socks I wear on longer runs.
