They were retail and to be quite honest I didn’t know they had a quad profile. I was able to buy them before being actually sold in the stores, and I bought tydan replacement blades from someone local and spoke to them about getting blades profiled and he recommended 7-12 and I had him profile them. I’m used to buying skates for myself and my son and just assumed they were standard blades. The guy does a lot of NHL and other high level player skates so I went with what he suggested and I guess either way my son needed tydan blades profiled, he mentioned he would have more blade on the ice, but he also probably didn’t know the pulse blades had a quad 0 on it. That being said I don’t know which profile he likes better. It took him a bit to get used to 7-12 but he seems ok for the most part. He’s a typical just turned 13 kid and doesn’t offer much info, just says he likes them. He also likes his shoes with holes and shirts with stains on them. I do see him slipping on crossovers which he never had an issue with. He’s a good skater who spends a lot of time working on it. I was looking to add more speed and acceleration and went with what was recommended, I spoke to a couple people and did the tydan assessement which recommended the 30/55. I probably should’ve left his blades alone but when I bought the tydan ones I figured I’d get them both profiled.
