Lange RX 130 Review: A Stiff All-Mountain Boot With Extra Forefoot Room

Introduction

The Lange RX 130 is a 130-flex all-mountain ski boot aimed at advanced and expert skiers who want a stiff, high-performance shell with a little more room than a race-derived boot. Compared with the RS 130, Lange gives the RX 130 a wider 100 mm forefoot last and a set of comfort-focused details, while keeping the same 130 flex rating.

That mix makes it a genuinely useful option for strong skiers. The boot still delivers the stiffness and edge-to-edge response that high-level all-mountain skiing demands, but it does not ask your foot to squeeze into a narrow, low-volume shell to get there.

This review covers who the RX 130 suits, where it performs best, and the details worth checking with a boot fitter before you buy.

Who the Lange RX 130 Is For

The RX 130 is built for advanced and expert skiers who ride all-mountain terrain at a high level and want a boot that keeps up with aggressive input.

It is also the better pick for anyone who does not have a very low-volume foot. The 100 mm forefoot last gives a couple of extra millimetres of space compared with the 97 mm last used across the RS line, which matters if your forefoot feels pinched in narrower boots.

If you want something slightly more comfortable than a pure race boot but are not willing to give up a stiff 130 flex, this is the model in the range that lines up with that brief.

Main Strengths: Stiff Flex and All-Mountain Performance

The headline figure is the 130 flex, and it is genuinely stiff. This is a boot for skiers who drive the front of the ski hard and want immediate response when they roll the boot onto edge.

GripWalk soles come pre-installed, so the boot arrives ready to walk in and matched to that binding standard from the start rather than requiring a separate purchase.

Inside, the RX 130 uses a full 3D liner. It is a fairly stiff liner, which supports the boot’s performance character, and it pairs with a spoiler at the back of the cuff for a more locked-in stance.

The moldable tongue uses a slightly softer material than the RS line, which adds a measure of comfort without softening the overall feel of the boot. A rubberized boot board reinforces the same idea. Where the RS boots use a stiff plastic boot board, the RX 130 uses a full-width rubberized version that absorbs shock a little better, which shows up on landings and in general all-around skiing.

Two flex adjustments at the back let you tune how progressive the boot feels, and an upper cuff adjustment allows lateral alignment of the cuff.

Fit and Comfort Details

The 100 mm forefoot last is the defining fit difference here. Three millimetres is not a dramatic change on paper, but it is often exactly what a skier with a slightly wider or higher-volume forefoot needs to avoid pressure points.

The liner is a full 3D build rather than a stripped-back race liner, and the softer moldable tongue adds cushioning across the top of the foot, an area where stiff boots tend to make themselves known.

Because the boot board is rubberized and full width, the ride underfoot is a little less harsh than a stiff plastic board, which helps on repeated landings and over long days.

How the RX 130 Differs From the RS Line

The RX 130 and the RS 130 share a 130 flex rating, but they are aimed at different skiers.

• Last width: the RX 130 uses a 100 mm forefoot last, while the RS line uses 97 mm.
• Boot board: the RX 130 has a rubberized, full-width boot board, while RS boots use stiff plastic.
• Tongue: the RX 130’s moldable tongue uses a softer material than the RS equivalent.
• Overall intent: the RX 130 leans a little more toward recreational all-mountain skiing, with more creature comforts built in.

In practice, that means the RX 130 trades a small amount of the RS line’s raw race-focused feel for more room and more comfort, while keeping the stiffness that advanced and expert skiers are looking for.

Things to Consider Before Buying

A 130 flex is stiff, and it is meant to be. Lighter or less aggressive skiers may find the boot demanding, and it rewards someone willing to work the boot rather than someone who wants a forgiving, softer ride.

The RX 130 is also the more recreational-oriented option in this pairing. If you specifically want the narrower, more race-like fit and feel of the RS line, the extra forefoot width here works against that goal rather than for it.

Fit is the other factor. The adjustments on board, two flex adjustments at the rear and an upper cuff adjustment for lateral alignment, give a fitter useful tools to work with, but they are not a substitute for starting with a shell that broadly matches your foot shape.

Buying Advice

Start with foot volume. If you have a low-volume foot and want the tightest possible performance fit, the RS line is the more logical starting point. If you have a little extra width in the forefoot, or you simply want a marginally more comfortable boot without dropping down in flex, the RX 130 is the more sensible choice.

Confirm the details before you commit: check that the GripWalk soles and your bindings are compatible, and have a fitter assess whether the 100 mm last matches your foot. Plan on having the moldable tongue and liner worked on if you want the full benefit of the comfort features.

This is a high-performance boot, and the quality of the fit is what determines whether it feels that way on snow.

Conclusion

The Lange RX 130 is a stiff, high-performance all-mountain boot that gives advanced and expert skiers a bit more room and a bit more comfort than a race-focused shell. The 100 mm forefoot last, pre-installed GripWalk soles, rubberized boot board, and softer moldable tongue are the details that separate it from the RS line, while the 130 flex keeps it firmly in performance territory.

If your foot wants a few extra millimetres and you still want a boot that responds the moment you pressure the front of the ski, the RX 130 belongs on your shortlist.
