“I rock these things everyday doing everything.”
— CrossFit Games Champion Jason Khalipa
There are two main problems we solved with the Rough Runner™ that other running shoes don’t address:
Problem #1
LATERAL STABILITY
Normal running shoes are “ankle-turners” because they’re made for you to run in a straight line on stable ground, like pavement. When you move side to side, like we do, that creates problems and increased injury risk. Rough Runner™ have added stability, laterally around the ankle and under foot to let you do more, to include heavy weight training, running, and ruck running.
Problem #2
0% MARSHMALLOW FOAM FOR BETTER SUPPORT
Typical running shoes on the market use what we’ll call “marshmallow foam” under your foot. It’s squishy and soft. Like a waterbed, it might feel good for a bit, but it’s terrible for your body. Marshmallow foam also compresses very quickly, even when it’s high quality, which makes your shoes feel “dead” much faster. What that does is that it encourages you to buy more shoes. That’s fine for some, but we wanted to build a stable platform under your foot, too — good for high mileage and all the other things (not just running) that you want to do with your life.
Rough Runner™ will last longer and perform better for all who live on their feet, from endurance ruck/running junkies to the Fight Club Class taking 20K steps a day just doing the work.
Versatile Road-to-Trail Outsole
Pound the pavement or go off-road. Two different rubber compounds form a single, seamless rubber outsole that performs in even the most demanding terrain.
The forefoot rubber is formulated for increased grip and the heel is dense, durable and won't wear down after miles of running or ruck running.
Lightweight Mesh Upper
Seamless, one-piece 100D polyester mesh provides breathability and flexibility without cramping your toes. At 330 g/sqm it's the ideal balance of weight and toughness.
High-wear areas are reinforced with a protective TPU film. We targeted the toe area for abrasion resistance and the midfoot to heel area for additional lockdown support.
10mm Offset
A 10mm heel-to-toe drop allows for the ideal balance between a running stride and a rucking gait. You have enough of a lift to reduce the strain on your achilles and support your heel strike while still controlling your cadence.
3D Molded Heel Lock
Comfortable PU foam bolsters lock in the heel to prevent slippage and excessive movement around the ankle. This allows you to secure your heel into the shoe without relying on lace-locking or lacing too tightly.
Anatomically Molded TPU Heel Counter
Anchors your foot with a supportive, injection molded heel counter that stabilizes your heel when you're moving with momentum.
Custom High Density Insert
Dense, PU foam insert custom made to fit the contours of the foot supporting all three (3) arches of the foot — yes, you have three arches in your foot (the medial longitudinal arch, the lateral longitudinal arch and the anterior transverse arch).
No MARSHMALLOW Midsole
Gradient Density™ EVA
Gradient Density™ means the midsole has more bounce under the ball of your foot and gradually becomes more stable towards your heel. It's uniquely formulated to provide cushioning and rebound with better long-term durability than any other running shoe on the market. No marshmallows here.
