Which should you buy? Our verdict on both, pulled from our full The Best Heated Insoles: 4 Compared (and One to Skip) comparison.
Fieldsheer wins on a built-in, stated-capacity battery and app control. ActionHeat is the better-documented buy for runtime per setting at a lower tier.

Fieldsheer (Mobile Warming) Premium BT Wireless Heated Insoles
Buy itThe most fully specified insole in the field: built-in 2200 mAh battery, four heat levels, and phone control through the maker's app.
- The battery is built into each insole and the maker lists it as 3.7V lithium-ion, 2200 mAh, so there is no calf-mounted pack or cable to route.
- Four heat levels and Bluetooth control through the MW Connect app on a phone or smartwatch, plus a waterproof touch button on the insole itself.
- Marked with multiple size guides for trimming, and charges over USB-C with a split cable included.
- The maker gives two runtime figures on the same page (7+ hours and up to 9 hours) and no runtime at each heat level.
- The page does not say the insoles suit ski or snowboard boots; it names snow boots, workwear, and cold-weather footwear in general.
- Heat is a single zone under the toes, and some sizes were shown as unavailable when we loaded the page.

ActionHeat Rechargeable Heated Insoles with Remote (AH-INS-LI-01)
Buy itA key-fob remote, three heat settings, and a stated runtime at every setting at a lower tier than the Bluetooth options.
- The maker lists a runtime for each setting: about 3+ hours on high (140°F), 5+ hours on medium (120°F), and 8+ hours on low (100°F).
- A wireless remote with three settings, with buttons on the back of the insoles as a backup.
- Cut-to-fit sizing with a guide, in two size ranges, and a dual micro-USB cable included.
- The page does not give the battery capacity in mAh, so you cannot compare it against the other batteries on paper.
- Heat panels sit under the toes only, and the page does not state a zone count.
- The page says they fit all types of footwear and boots but does not mention ski or snowboard boots by name.
