Continually Testing


For this review, we have a rolling update continuously in the works. Every time a new shoe is released, we order it and start testing it. We compare it side-by-side to the earlier models that we loved and evaluate what is new with each recently released design. This model allows us the luxury of testing and comparing previous versions to the newest iterations of these popular shoes so that our discussion of features, changes, and additions is relevant.

These pairs of shoes aren't going to test themselves.

How We Test


We spent months logging at least 15 miles per shoe, mixing between short, slow and fast, one-mile runs to consider different strides and foot strikes and six-mile runs to see what comes out after a good bit of rubbing and pounding. We hit trails, sandy beaches, granite staircases, and steep mountain roads, but most of the miles came from open, flat roads, where most road runners do the most mental work.

Where We Tested


We researched materials and product claims and scrutinized every detail of some of the best road running shoes in existence to bring you this review. We have gone from hitting the mountain roads of Thomas Jefferson's Appalachia in Virginia to the beautiful, unrelentingly flat, and sometimes surprisingly hot and muggy streetscape of Norfolk, Virginia and its neighboring Virginia Beach. It's a region rich in history stemming from perhaps 10,000 years ago with archaic and then paleo-Indian populations through European Colonization, Independence, the Civil War, and both World Wars. It also serves as the home for the largest naval station in the world and one of the ten busiest seaports in the nation. This group of road running footwear has been put through our rigorous standard of testing. Be relieved to know that we did the dirty work for you, exposing without bias each model to the trial of miles, logging dozens of miles and putting in a heavy dose of extracurricular abuse.

Each of these puppies goes through miles of suffering  prodding  tinkering  and research before we finish our review.
