The Adidas Hydro Pro is a boot with a neoprene ankle cuff made specifically for canyoneering. The canyoneering boot is made to fit specifically with a neoprene bootie.  Over the last couple months Pura Vida Adventures has tested it in the canyons of Utah, Arizona, and North Carolina. Below is our review of the Adidas Hydro Pro boot.
Reviews are based out of 5 stars:
Comfort 3.5 stars
The Hydro Pro Boot is by no means uncomfortable, in fact after breaking it in and getting use to it I found it more comfortable then the Five Ten Canyoneer, which has been the standard in Canyoneering boots over the past few years. The fit in the width is a more normal fit then the Canyoneer which seemed to have a fit to wide for the normal foot.  The lacing system which includes velcro, quick lace, and a zipper creates a secure fit which tucks everything very nicely into the shoe.  Like any boot with a neoprene ankle it is not as comfortable as a trail shoe but what it lacks in comfort it makes up for in warmth and ankle support.
Durability 4.5 stars
This category is what has been lacking in many canyoneering shoes of the past. Typically wear in the canyoneering boot can be seen within a half dozen uses, however after over two dozen canyon descents in the Adidas Hydro Pro I am still not seeing anywhere from use. It seems this boot is built to last.
Performance 4 stars
The biggest question about this shoe was its performance. Would the rubber stick well to wet surfaces?  The resounding answer is yes on both wet and dry sandstone and granite this boot performed. Five Ten rubber which is thought to be the pinnacle in sticky rubber out performs the Hydro Pro but only in a subtle way.
Overall 4 stars
The Hydro Pro lacing and buckle system is great providing warmth and stability.  The performance of the rubber was impressive and exceeded expectations. The best thing the Hydro Pro has to offer that other canyon boots have not offered in the past  is durability.
