I've heard many people voicing dislike of the higher heel in Jacksons. So I feel compelled to counter with my personal positive experience, and some logical deductions.
When I was still in Riedells, I always found it hard to get off my toe pick for any kind of move. Then I switched to Jackson (moving my same blades over to the new boot) and suddenly found it so much easier to get off my toe picks and skate on the main rocker. My conjecture is that this was because I have fairly tight calves and Achilles tendons, making my foot more plantar flexed when in a relaxed position. The higher heel might help with adjusting for this plantar flexed position.
The bottom line is, each person has different feet and each boot manufacturer is suited to a subset of skaters with that particular type of foot. Just because some skaters complain about the heel height doesn't mean everyone should stay away. Jacksons is still very much in business, so apparently the heel height must suit a sizeable subset of skaters.
Haha, I live in high heels and don't have any complaints in the slightest about Jackson Fusions' heel heights, nor do I feel like I'm tipping forward.
