Merrell describes the Antora 4 as a trainer for women who are on the move, and the specification backs that up. There is foam in two places for cushioning, flex grooves that let the sole bend with your foot, and a rubber outsole intended for confident footing on hiking terrain. It aims at light to moderate trails rather than extreme mountain use, and that clear purpose is exactly what makes it useful.
The shape is low and clean with a padded collar and a generous midsole profile that visually reinforces the cushioned feel. The Aqua colour gives it a fresh, sporty look that stands out from the usual black and grey trail trainers. It is technical without shouting about it, so it works with leggings, shorts and outdoor trousers and does not look out of place on the high street.
FloatPro™ appears twice. The foam footbed is intended to cushion and return energy, and the midsole foam is described as comfortable, light and durable. The FLEXconnect™ grooves help the shoe flex in two directions, which makes it feel less stiff when you change surface from tarmac to earth. Together with the padded collar and heel construction, this makes for a shoe that suits short and medium outings, brisk walks and long days on your feet.
The toe cap and the TPU reinforcements are there for the knocks that trail use brings. The Quantum Grip™ outsole is designed by Merrell for demanding hiking terrain. We would recommend them for easy and moderate paths, parks, farm tracks, forest roads and active urban use. We would not sell them as high-mountain shoes, for very deep mud or for aggressive, rocky technical terrain.
Do not choose them if you need to stay completely dry: this reference is not the Waterproof version, which Merrell sells as a separate line. They are also not the first choice for pure road running or for deep mud.

If you are between two sizes, choose the larger one if you want a looser fit or wear thick socks. Choose your usual size for a closer fit. Measure your feet at the end of the day. If you have a high instep or wide foot, remember that some models fit more tightly across the instep.
Are the Merrell Antora 4 waterproof?
No. This is the standard Antora 4. The waterproof version is a separate model.
Are they only for trail running?
No. Merrell lists trail running and everyday use, so they also work for active daily wear.
What gives the cushioning?
FloatPro™ foam, in both the footbed and the midsole.
Do they grip on paths and tracks?
Yes, they use the Merrell Quantum Grip™ rubber outsole, designed for confident footing on hiking terrain.
Do they keep dirt out?
Yes, up to a point. The gusseted tongue helps prevent earth and small particles from getting in.
Can I wear them for walking in town?
Yes. The cushioning and low profile make them comfortable for city walking.
Delivery anywhere in Europe takes 4 to 6 working days. Shipping is charged by destination country and calculated at checkout. Returns from outside Spain are at the customer's expense.
If you want comfort, grip and a design that works on the trail and in town, then yes. If you need a waterproof shoe or pure road running feel, then look at another model.
