Rose Anvil Boot Breaker Insoles

I've just been gifted a brand new pair of boots. I've been in Sneakers and casual dress shoes for the last 10 years or so. Walking around my house to get a feel for the boots, they're definitely a bit stiffer on the foot that what I've grown accustomed to. I've seen a lot of ads and videos on the Rose Anvil Breaker Insoles and would love to hear from this community on their opinions or any recommended alternatives. Appreciate any and all feedback. Thanks!!!
