Under Armour is currently a leader in performance apparel. Just from my personal use, I find that Under Armour is durable, stylish, true to size, and functional; however, it can be expensive.
To continue expanding to a variety of sports and activities to increase brand visibility.
Having the best marketing like you do, and being closer to customers.
I believe that your brand is top notch that stands out because it doesn't try to conform to any other brand out there. However the price point can be a little high and I believe if lowered slightly it could help push the brand forward.
I think trying to branch out to different sports that aren't as mainstream would be beneficial.
Customization of products such as shoes where the customer can go online and choose the colors and design of their choice to own a one of a kind item.
I know that brands are always looking to improve, to develop the next best thing, that next big thing. And that's what makes sporting apparel and sporting goods so competitive. Everyone is always looking for that edge in whatever it is that they're doing.
