Is the Merrell ProMorph good for trail running?

Yes. It is built as a trail shoe with a Vibram XS Trek EVA outsole, a flexible midsole and a breathable mesh upper. It suits shorter to mid-distance trail runs more than long, rocky efforts.

How much cushioning does the FloatPro+ midsole give?

It is a light, responsive foam rather than a max-cushion setup. Runners wanting plush landings for long distances may want a higher-stack shoe.

What sizes and widths does it come in?

It is listed in women's sizes 5 to 11 in medium width. There is no wide option in this listing, so wide-footed runners should size up or look elsewhere.

Can I use it on roads as well as trails?

The flex grooves and light foam work fine on pavement, but the trail-oriented outsole is happiest on dirt and gravel. It is a reasonable door-to-trail shoe.

One pair of shoes with the removable recycled EVA foam footbed already fitted. Nothing else is included.

Is the ProMorph waterproof?

The build is mesh and synthetic with a breathable lining, so it drains and dries rather than sealing water out. Expect wet feet in heavy rain or deep puddles.
