Though Crosskix probably wouldn't appreciate the comparison, for the sake of simplicity I'll say these representatives of foam composite footwear are like Crocs for CrossFitters. Yes, you can slip them on and wear them casually to BBQs, on beer runs, or to the pool (they even float!) But these mold-injected shoes are also durable enough for wear during workouts, including CrossFit training, Tough Mudders, and even marathon running.
Available in sizes and styles for men, women, and children Crosskix have a fully adjustable inset strap (Velcro attachable) for personal fit, plus a full-coverage design with several air/water vents to promote breathability. Their LITEKIX high-grade EVA materials were chosen to absorb high impact without compromising flexibility. And while Crosskix are not the most beauteous shoes I've ever seen, at least they've made an effort to blend in with standard athletic shoe aesthetics without losing their functionality.
Crosskix are also 100% amphibious, game both for tromps through muddy puddles and full submersion in water. Rear drains will keep them from getting water logged.
