What is the Delta Activ?

The Delta Activ is a supportive, exceptionally comfortable and durable three-season mountain and hill walking boot. Using a Gore-Tex membrane and Vibram sole unit, they're fully waterproof and secure enough for even the muddiest of treks.

What are they made from?

Upper: Featuring a classic design, the Delta Activ's are made using 2.4-2.6mm thick high quality full grain leather. Scarpa amazingly only use two pieces of leather over the entire upper of the boot, this reduces the amount holes pierced into the fabric and also reduces the chance of a seam snagging or coming loose over time. The heel features a reinforced section of additional leather for greater durability. 

Membrane: Underneath this you'll find a fully waterproof Gore-Tex membrane, keeping your feet dry and comfortable. 

What are the features?

Vibram Biometric: This mind-bending technology takes footwear support and comfort to a new level. To offer the greatest level of comfort, support and stiffness, Scarpa use a midsole which features a clever design, placing thicker areas of stiff plastic in areas which require support, and thinner plastic in areas that require flexibility. The same principles are applied when adding cushioning; the heel and forefoot gets a thick area of cushioning, while the arch and toe area receives less due to where you apply pressure when walking. The outsole then features lugs which are shaped and positioned differently depending where the sit on the boot; lugs on the outer are thinner and closer together for maximum grip, while centre lugs are thicker and widely spaced apart to self-clean as you walk. 

Other features include a footbed designed to offer support in certain places of your foot for greater comfort during long walks, memory foam inserts in the heel area which mould to the shape of your foot, Scarpa's V-Flex system which ensures the collar of the boot will flex easily backwards and forwards but not side to side, a Speed Lacing system which uses wheels on each eyelet rather than a simple loop to allow an even tension over the boot, and lastly the ability for the boot to be re-soled. Mind melted yet?

How do they fit?

The Delta features a fairly wide heel, a square toe-box shape and a relatively average width. The volume of the boot is quite high, so if you find your foot isn't filling the boot (height wise), we'd recommend the use of a volume reducer. If the Delta's fit your feet they really are a dream to wear, the memory foam and comfortable footbed makes them feel like a slipper when out in the hills.


This seeminly traditional leather walking boot is packed with tech to make life in the hills as comfortable and enjoyable as possible. Use them for mountain walking, hill walking and trekking over long periods of time.

Care & Advice

Here at Trekitt we know all too well of the difficulties people face when purchasing footwear online. The hardest part is being confident that you have picked the correct fitting footwear, so that is what we will cover in this blog (or if you prefer you can CLICK HERE to watch our video).

In our Hereford shop we offer a professional boot fitting service where we assess your feet, find a selection of boots that match you foot shape and most importantly we make sure that they are comfortable. This is easy to do in the shop, where we have access to the right tools, the option of letting you try on as many styles as you like and a knowledgeable member of staff that can communicate directly with you regarding your needs.

But let’s not dwell on what you don’t have, instead we shall teach you how to ascertain your size using some common household objects.

What you will need:

  1. A piece of A4 paper
  2. A pen or pencil
  3. A floor and a flat wall
  4. A ruler or tape measure

What you need to do:

  1. Put on the socks that you intend to use with the footwear you have selected
  2. Place the paper/cardboard on the floor with one end flush against a wall
  3. Stand on the A4 paper with your heel pressed firmly against the wall and your foot pointed forward with the edge of your big toe aligned with the edge of the paper.
  4. Draw a line just in front of your big toe
  5. Measure the distance from the wall edge of the paper to the line you drew
  6. Repeat the process for the other foot
  7. Finally, check the longer of the two measurements against the table below to find your size
Your measurement (cm) UK Size EU Size
21.7 3 35
22.1 3.5 36
22.5 4 37
22.9 4.5 37.5
23.3 5 38
23.7 5.5 39
24.1 6 39.5
24.5 6.5 40
24.9 7 41
25.4 7.5 41.5
25.8 8 42
26.2 8.5 42.5
26.6 9 43
27 9.5 44
27.4 10 44.5
27.8 10.5 45
28.3 11 46
28.8 11.5 46.5
29.2 12 47
29.6 12.5 47.5
30 13 48
30.4 13.5 49

NOTE: The above table is only a guide. Manufactures don’t like to make it easy as every single one of them strays from the measurements above.

So, once you have received your chosen footwear please take the time to do these simple tests to check they are actually the right size and that they fit the rest of your foot correctly.

The length test

  1. Whip out the removable footbed from the boots.
  2. Put them on the floor about shoulder-width apart.
  3. With your socks on, stand on the footbeds making sure that your heels are right to the back of the heel cup.
  4. You should now be able to see approximately 2 cm (about an index fingers width) of the footbed poking out in front of your toes.

If you can see this amount of space then you are pretty much on the way to making sure that your boots are the correct size. This space between your toes and the end of the footbed ensures that you will not stub your toes on the inside of the boot when you descend. This can be excruciatingly painful. If you can’t see this amount of space then it’s a good bet that the boots will be too small.

The heel lift test

This test will tell you if the shape of the internal heel cup matches your heel to ensure it holds you securely, especially when ascending steep ground. We are trying to eliminate the dreaded heel blister.

Before you commence this test it is imperative that you have laced the boots correctly.

  1. Tap your heel so it’s as far back in the boot as possible, being sure to keep your foot at a right angle to your leg at all times during the next few steps.
  2. Make sure that the laces have no slack in them across the forefoot by starting at the front of the boot and working the slack backwards and to the top. You should just be able to squeeze the end section of your finger under the laces, not easily, but just about.
  3. If you are wearing shoes then ensure the last upper part of the lacing is tight, not cutting off your circulation tight, but certainly comfortably snug as this will hold your heel back in the heel cup and will reduce any excess slipping (If you are wearing boots, this will be the eyelets that sit just below/inline the ankle).
  4. Please also make sure when trying out boots that use all the lace hooks, don’t be tempted to leave the top one undone as your foot needs to be held securely right in the back of the boot.
  5. Now that your boots are done up properly stand up on your tiptoes and walk on the spot on the balls of your feet as if you are walking up a steep hill. If your heels lift more than approximately 5mm from the footbed you may need to pull the laces tighter, or the boots may just be the wrong shape for you.

The toe wiggle test

This test is designed to check whether you have enough room around your toes. Your toes need to be in a happy place, they need plenty of room to wiggle without being squashed together, or cramped in from above. However they don’t want to be swimming around in acres of space either, this will cause friction blisters and stability problems when traversing hillsides. So, with the boots done up properly, walk around your house and make sure that your toes can wiggle freely.

Home Trial Period

However, even after the most rigorous assessment and testing, there is no better way to be absolutely sure than to have the boots on your feet for an extended period of time. We therefore offer our Home Trial Period which gives you the opportunity to wear the boots around your house to give you an indication of how they feel before you venture outside. We recommend that during the Home Trial Period that you wear the boots for as long as possible and at different times of the day, wear them up and down stairs, when moving around and when resting, you can even sleep in them if you want. 

IMPORTANT NOTICE: During the Home Trial Period we insist that the boots are worn indoors only. All footwear must be returned in a new and perfect condition with the original packaging and a proof of purchase. We retain the right to refuse to refund or exchange if footwear shows any sign of being worn outside.
