Daiso USA (in-store CA, TX, NY) - Good Insoles for $1.50

Sure, these are not the $40 Superfeet insoles with multiple level foam/plastic injection molding, but to replace my Ortholites that came stock with my Salomon boots, I found that my local Daiso discount store carries a wide variety of insoles with one that fit and feels perfect. They do have softer, harder, and memory gel insoles - most from China or Vietnam.

(I chose these harder insoles https://www.daisojapan.com/p-3696...-8pks.aspx.)

No point spending more than $2 on an insole in most regular use cases since these are almost all made in Asia (when shipped with the shoe new), so don't get ripped off by the 'branding' and 'hype' behind these "pieces of foam and plastic of different density molded together". Naturally, if you're doing ultra-marathons or hiking K2, you don't necessarily want to go cheap because your feet may kill you, but few do extreme activities like that.

Do keep in mind that the shoe's main cushioning and feel comes from the foam underfoot, so you won't be able to turn a soft shoe into a stiff hiking shoe with insoles - you'll need to switch shoes instead. Insole replacements for boots like my Salomon make sense since the rest of the shoe (leather, sole, etc) are built so well, they easily outlast the insoles.

If you are wearing the latest 'faux athletic' single density fabric-upper + single-density-white-foam sole that you see everywhere nowadays, starting at $10 at Walmart for those Avias to those more expensive Nikes at $50, insoles may not make a difference given that these were all designed to go flat in a year and be tossed out for the next pair.
