Altra Lone Peak 4.0 RSM Low Women’s Shoe – First look

Altra Lone Peak 4.0 RSM Low Women's Shoe Review - First look

Everyone who spends a few minutes with me will know that I love Altra shoes.  I have been wearing them on the trail for the past two years and I also wear them for jogging, walking and relaxing!

My Lone Peak 3.0 Neoshell Low shoes have been on their last paces for a few months now. With over 1000 km done, it was time to retire my current Lone Peaks and I have been desperately wanting to replace them with the Lone Peak 4.0 RSM Low Women’s shoe but found them hard to source. I finally succumbed to ordering them online from Amazon Australia and was surprised when they were shipped direct from Amazon US!

The first thing I noticed out of the box is that the sole of the shoe has been beefed up.  The Lone Peak 3.0’s were very grippy and the 4.0’s are more so. The Altra Trailclaw technology positions lugs beneath your toes for better traction and the Maxtrac provides a combination of grip, traction and durability. The stone guard layer between the sole and the shoe upper, has also been beefed up and appears to be slightly deeper and sturdier.

The usual features of the Lone Peak are there including the Fit4Her technology, gaiter trap, generous toe box and the Zero Drop design. Altra is known for its Zero Drop shoes which means that from your heel to your toes the foot bed is level unlike most shoes that are higher at the heel. This Zero Drop feature make you feel you’re leaning back ever so slightly which is noticeable the first time you wear them. The high-level cushioning in the Lone Peaks means that you won’t need to speed a lot of time transitioning into the shoe.

Having purchased the 4.0’s online I was very pleased to discover that the sizing hasn’t changed. I’m wearing the women’s US 9.5 again. However I did notice that my 3.0’s have stretched quite a bit with wear!

I was underwhelmed by the colour options – Gray or Gray/Purple – and more so because I could only purchase Gray in my size. The worse part is my new hikers are grey with a teal trim and everyone knows how much I love teal … not!

In case you’re wondering, RSM stands for ‘rain, snow and mud’. Of course! I prefer the RSM shoe because it is waterproof and the new eVent fabric prevents water entry but is also breathable to allow heat and sweat to vent out of the shoe. I also find the waterproof shoe reduces dust and dirt collecting over your socks.

To date I have only worn the Lone Peak 4.0 RSM Low Women’s shoe on shorter day hikes but will be wearing them on the Hume and Hovell Track in the coming months. So far I am very pleased!

We like

  • These are some of the lightest hiking shoes I own and after long days hiking this makes a difference
  • The shoes are narrow in the heel and wide in the toe box. I wore a pair of Keen Targhee II Mid Women’s Boot in the past and they are too wide for me at the rear of the shoe
  • The cushioning lasts well and like the previous model, I would expect 1000 km of use. The thing that will make you throw them away is the loss of traction however given that has been beefed up, I don’t think this is an issue
  • I particularly like the cushioning layer for concrete, bitumen and hard management trails
  • The traction is very good on a variety of surfaces
  • They breathe well so your feet don’t overheat. They also dry reasonably quickly in warm weather when they get wet
  • The toe guard provides great protection for the front of the foot
  • The Gaiter Trap works well with the lycra style gaiters such as the Dirty Girl or Altra Trail Gaiters

What don't like

  • Unnecessarily difficult to source in Australia – lucky we’re living in a connected world!
  • A choice of only two colours and only Gray (with a teal trim) available in my size

Best uses

  • Hard surfaces and trails
  • For hikers with a wide forefoot and a narrowish heel
  • When you need great cushioning on those big days
  • At $240 they are not cheap but should last you a couple of years or around 1000 km (whichever comes first)

Other Versions

  • Men’s version Altra Lone Peak 4.0
  • The Altra Lone Peak 4.0 also comes in a mid version which provides greater ankle support and protection
  • Altra does a non waterproof version of the Lone Peak 4.o which is lighter and great for warmer weather
  • The Altra Lone Peak 3.0 Neoshell Low Women’s shoe is still a great option and available on sale from a number of different outlets

These shoes come with a Gaiter Trap which is a fancy name for a velcro tab designed to suit the Altra Gaiters and which also works well with the Dirty Girl Gaiters. The gaiters are only designed to keep ‘stuff’ out of your shoes which is a godsend in sandy or burr ridden environments

The latest version of the Altra Lone Peak 4.0 RSM Low is both waterproof and breathable. The gaiters hook can be seen on the front just below the laces
