If you’ve ever watched a John Hill vlog you know that he never holds back. He recently made a vlog and titled it “THE TRUTH ABOUT SKATER TRAINERS”. The video isn't all about Skater Trainers so if you wanted to watch it you can skip to 6:35 to get the part about Skater Trainers. John and his friends do some killer tricks on the SkaterTrainers.
John goes on to say “I think what they're supposed to do is invoke a sense of confidence. Because confidence is more than 50% of skateboarding.”
John talks about his 10 year old self and practicing on the grass he then says”cement is definitely a lot better to get pop.” If you're interested in a pro skater opinion on Skater Trainers then definitely check it out.
