They all react to one another. When true Tim Ivey vh and started to offer custom skates at the retail stores, ccm and Bauer coincidentally started to advertise and push custom skates as well. Ya they were always available but they were never marketed to the mass.
True and ccm obviously created their quick release holders to compete with the edge holders. Ccm one piece boot I'd argue was to separate themselves from Bauer. This along with their 90 day guarantee helped them push their skates a lot.
At the end of the day it's good competition and forces each company to innovate better and provide better customer service as there are now more options out there.
