I just got my TopBoxer Win1's and wouldn't consider them very comparable to Winning. In terms of the softness of the outer padding only. Everything else is different. (Not necessarily worse, as the TopBoxer velcro is way better than the abysmal stock Winning velcro).
Honestly I would abandon the idea of a "cheaper winning" because that's basically what everyone tries and if it was that easy, it would be done by now.
On the topic of starting your own brand, I would love to hear from anyone who may have actually attempted to MAKE their own gloves. I think that's really the only way to do it otherwise it's all just pakistan/china clones, no? And unless you're a company that can control the process entirely like Rival or TopBoxer, then you are still in the same boat you were in at the beginning.
Of course starting from scratch means expensive. I'm thinking Fly and Onx. But at least you get something truly custom and different and new.
