Is the Pegasus 41 GORE-TEX good for daily running?

Yes. It is a neutral daily trainer with ReactX foam and two Air Zoom units, built for everyday road miles. The waterproof upper makes it a good pick for wet-weather training.

How does it differ from the regular Pegasus 41?

The ride, fit and midsole are the same. The GORE-TEX version adds a waterproof, less breathable upper and a bit of weight, so it suits wet and cold conditions better.

Does it run true to size?

Most owners say it fits true to size with a normal width, like the standard Pegasus 41. Runners who wear thick socks in winter may want a little extra room.

Can I use it for trail running?

It is a road shoe with a rubber outsole, not a trail shoe. It handles light gravel and wet pavement, but lacks the lugs and protection for rough trails.

Is it breathable enough for summer?

Less so than the regular Pegasus 41. The Gore-Tex membrane keeps water out but traps heat, so it is better for rain, cold and shoulder-season runs.

Is it fully waterproof?

The Gore-Tex membrane keeps rain and splashes out, but it is not designed for standing in deep water. Water can still enter over the collar in heavy flooding.
