S5 hardboot - Korean

Recommended Posts

Right, I had a chance to test out the S5 hardboot. I am pleasantly surprised how they ride.

In comparison to 951, the main differences are :

- heel sits much lower due to different heel placement (more deeluxe like) see below

- heel above causes increased sole length Vs same size upz or 951. For 951 and upz I used M size F2s, for S5 I would have to use L size. For me a major drawback. This is true for shell C in 951 and 302 shell in S5. Liner 285 mp

- spring system Vs 951 is little less user friendly. Requires a bit of creativity to get it adjusted. Takes more time to adjust on slope. Probably impossible without taking the boot off. I had to use a screwdriver to lift the shaft and wrench to get the two screws moving.
- I found the standard spring too short and had to exchange to something different - standard lenght of the spring picture on the left vs donor spring on the right (mind you I cranked it down quite heavily which might have influenced the reaction time of the boot to lighting fast, but it also makes you think that if you have cranked it up so much, why do you need a spring at all?)

- They are super reactive and comfortable. If 951 shell is too narrow for you S5 might be your choice. The shell is wider in the foot area

As a standard they come with 3 tongues and 5 different springs.

- the buckles look a little cheap, but in general they work fine. Also the design with the cable/clasp over tongue does not affect the flexing motion of the boot.

This is a good alternative if you dont have all the money in the world to spend on 951, but still want to get the northwave shell shape with a few tweaks.

if you have any further questions I am happy to answer.

regards

This is great!  Thank you for taking the time to write it out.

The Spring system on S5 seems to went through a few iteration. 
There are some pic floating around showing it comes with stock Deeluxe type of mechanism.  The close up you provided are great and show problem area.  
Seems like a better mouse trap(spring) can be made for those with the how-to?
I wonder since some of the part(spring/buckle)/design are from Deeluxe; wonder if some of the parts can be "ported" over; BTS/DGSS and etc. *

In term of fitment:
The foot area is wider than 951.  How does the heel area compare to UPZ/951?  same great heel hold snugness?

"They are roomier than 951. Heel hold the same. Heel sits much lower than in 951."  <-- edited.  Your already answered this in your for sale thread.

in term of plastic stiffness:
How does it compare to 951/UPZ/Deeluxe?

My biggest concern is fitment not so much price: 
I think these boots might fit my feet better as I am in between size.  
Because of this statement:

I think this is the reason why you have to go up a size for binding?

"The Northwave copy boots we produce are made from low shells (272,282, 292,302) in 10mm increments to increase the fit.  For example, a 255 mm, 260 mm mermaid uses a 282 mm shell.  The 265mm, 270mm mermaid uses a 292mm shell.  So the length of the shell is 5mm ~ 15mm smaller than the boots of other companies, and the fit feeling is excellent like custom shoes."

Where can you buy these boots?  I need 292mm shell otherwise I would have bought your in a heart beat.

For 951 i use C shell for 285 mm foot with zipfit liner.

Normally I would have to go to D shell to get the right size.

When I do barefoot shell test with my C shells I have a little less then one finger left, which is superb fit.

In S5 I have to take 302 shell which requires an L size binding due to sole size and heel placement.

Most likely I have managed to fit myself into smaller shell in 951 then I should. Maybe I could go into smaller shell in S5 but that would require another purchase and before I sell current 302 shell I am not purchasing anything else 😉

Plastic feels a touch softer then 951 standard shell, but bear in mind that flex control comes mainly from the spring.

I bought these boots via Facebook link here :

this is the guy who produces them.

most likely dgss or BTS could support this shell given the fact that deeluxe springs fit.

@slapos  the lower spring attach lug looks a little flimsy in the pictures - is it beefier than it appears ?

Sorry @slapos I should have been clearer. I was asking about the shell lug where the lower end of the spring attaches.

hi Lurch,

no worries - my english is not always where I would like it to be.

i think its sturdy enough - I guess you would have to touch and feel.

unfortunately I spend so little time in the mountains these times (4 hours top per week, if the winter is good) I dont have much time experiment. 

These boots seem compatible with all spring kits that have been made for deeluxe. I think they could be really good for Extreme carving as they have a huge range of motion, which is not limited by buckling system or plastic interference.

All in all this boot proved to be much better then I expected.

@charliechocolate Do you have the stock liners in your UPZs? After mine had worn out I replaced them with Palau TF, and now my wife is jealous because my UPZs are much lighter than hers with the stock liners. Those are very heavy.

FWIW, my daughter rides RC10 with Deeluxe liners. My wife has RC8 with stock liners (same shell size). The ones with the stock liners weigh a hair under 6 lbs per piece. The ones with the Deeluxe liners weigh slightly over 4.6 lbs. Not sure how the different plastics contribute, though.
