ThermalStep Rechargeable Heated Slippers vs Amiable Heated Slippers

Both slippers heat to 140 F, so the real split is battery life and construction. The ThermalStep runs up to 11 hours on its included 7.4V batteries and has a plush lining, while the Amiable packs a larger 5000 mAh battery but takes about 5.5 hours to charge and comes in cotton and rubber. Owners of the ThermalStep report quick relief for cold and numb feet, including Raynaud's, and say the heat lasts; the Amiable is the simpler, roomier pick for lounging. Buy the ThermalStep for longer wear and a softer lining, the Amiable for a bigger battery and a wider fit.

• Choose the ThermalStep if you want the longest runtime, a plush lining and heat that reaches the toes and soles.
• Choose the Amiable if you want a larger battery, a cotton upper and a roomier men's 9-12 fit.
