Are they comfortable to walk around on or can you feel the wires inside?

A lot depends on your boots, your socks and your terrain. I can definitely feel the wires through my thin Smartwool socks, but it's only intermittently bothersome. No matter how I wrap the extra cord or tuck them into my boot tongues, I have to reach down and pull the wires up multiple times a day or re-tuck the Velcro. Part of this is due to jarring from skiing black to double-black terrain (bumps, trees, drops, etc.) I wouldn't notice wires if I were skiing gentle groomers and wearing thicker socks. Repeated up-and-down motion jars everything loose, especially plugs from their sockets, turning off the heat. This is my biggest gripe.

How long are they running on full power ?

I need a pretty cold day (sub-10° F) and poorly insulated boots to run full power longer than 20-30 minutes. I usually run at 50-75%, but I sometimes need full power at elevations above 11,000 feet or in the morning when ski boots are cold. Full power drives out end-of-day clamminess but it causes excessive perspiration earlier, which leads to clamminess when the temperature drops. Re-reading your question, maybe you wanted to know how long the batteries will last at full power? Answer: unknown – they are too hot to test at 100% power in 0° F and above with normal boots. Maybe somebody else has extended sub-zero experience with them. PS, I have chronically cold feet.

The toe shape does not match my boot. Can you cut the front/toe section without cutting the circuit?

yes, you can cut the front section more. Even if the heating element is cut, the insole can still work normally.

How do you order a size?

You cut them to fit your feet or bottom of the shoe.
