yes, i also noticed the stability issue when i walked around, it amplifies my tendencies to tilt outwards on my heels. Changing to a thinner and firmer insoles did help marginally as an initial impression, but unsure how it translate during actual run. Perhaps a heel guide can be added to the shoe to address this issue.
Neither do i like the slow and significantly deep compression before returning to original. From theoretic point of view, this feels like a loss in momentum, especially it led to stability issue (wobbling on the heel part). As for walking, this could make one feel cushy and nice though. Like you said, if one does not have stability issue, this may be one's cup of tea.
Am going to with another thinner and hopefully firmer insole to compare before deciding if i want to keep this.
