Who has landed here knows quite sure what an elastic lacing system may (or may want!). That is why I will spare me detailed explanations and come straight to the core.
I have normal shoe size 42-43 (in running shoes usually 44 to 44.5), my running shoes have 10 eyelets (5 on each side, without counting the topmost Rückfädel-hole), with Rückfädel hole there are therefore 12 eyelets (6 on each side) and the distance between the eyelets (left-right) is 5 cm.
After the history here is the discussion of the individual elastic lacing systems in detail:
*** Nathan Lock Laces:
1) The threading works like normal, non-elastic laces. It contrives the Nathan Lock Laces from the bottom up, which simply makes the Marathonschnürung also. No "To-the-corner-thinking" necessary. The laces are long enough for a Marathonschnürung.
2) The threading can easily be carried out at not tightened shoe because a later readjustment is easily possible.
3) The lace ends are coated with a plastic film formed into needles (pins) which facilitate the threading in the holes. In the manual it is recommended to cut off the excess length and to clip the ends in the supplied plastic part to secure them against fraying. I did not do it, because this use in another shoe (threading!) Is unnecessarily difficult or impossible. The threading of Nathan Lock Laces in the holes of the shoe is (at least) the Saucony running shoe a little difficult because the Nathan Lock Laces are as the Yankz Shure Laces thicker and the needle just so fits through the hole in the shoe. Without needle threading would in my opinion impossible.
4) The two ends of Nathan Lock Laces are inserted at the top of the shoe through the cord lock and then hold bombproof. The handle of the Tanka must be already operated very strongly to the opening large enough to get so that the laces through fits! The supplied plastic part to clip to the ends of the shoe band I have not used (see point 3), but otherwise resolved (see photo).
5) If you your running shoes (especially in the heel) does not fit 100% You may Nathan Lock Laces Thread in Marathonschnürung (see item 1). The rubber-laces of Nathan is noticeably stronger than the Yankz Shure-Laces, the heel grip is very good.
6) Once set and the shoe sits permanently well at the foot without pressing.
7) The adjustment makes a robust impression.
8) Attach the popular champion-time measuring chip (by threading) is with Nathan Lock Laces possible (if you do not shorten the ends as recommended by the manufacturer and stored in plastic clip, but as under point 4 of my recommended knotted).
*** Xtenex-Laces:
The Xtenex-Laces with a length of 75 cm should lt. Homepage be ideal for me. In my opinion, they are (borderline) short and could quiet 5 cm longer (can cut you always some) be.
1) The threading works fine if you stick to the instructions (if in doubt, visit the US Xtenex website a good video tutorial)!
2) make sure the threading with relay shoe and never overtighten begin the cords, but rather too loose! They underestimated the resilience of the rubber initially very fast times and then presses the shoe. I cords so loose that above the last hole protrude only 1-2 knots.
3) The lace ends are coated with a plastic film formed into needles (pins) which facilitate the threading in the holes.
4) the first run as "Einstelllauf" look, so take time to recreate the shoelaces. Ie stop on the first few kilometers from time to time and adjust here and there one or two holes is unfortunately normal (for me). For long runs "grow" In addition, the feet a little bit, so again: "Not too tight adjust". A joint operation with training counterparts would agonizingly (for colleagues). Running it for the first time so better alone.
5) If you your running shoes (especially in the heel) does not fit 100% - Stay away from the Xtenex!
That may now "dared" sound, but if they are to try it anyway they quickly determine that the Xtenex-Laces particularly at the upper shoe edge (top hole) can not be so strapped that the heel sufficiently gets support in the shoe when the shoe does not fit 100%. With a conventional non-elastic lacing system can better manage here (keyword "Marathonschnürung"). This is by design with the Xtenex-Laces and also because of the short length of the laces is not possible! If you stretch the Xtenex-Laces up very strongly to get better grip on the heel, they are hardly in the shoe into it, but still the heel will not provide adequate support.
6) Once the above procedure "survived" and of shoe sits permanently well at the foot without pressing.
7) No, the nodules in the shoelace not push! If they feel that they press the nodule, then they have the shoe most likely tied too tightly.
8) Attach the popular champion-time measuring chip (by threading) is the Xtenex-Laces difficult or inconvenient (unless you secured the chip eg with a cable tie).
*** Yankz Shure Laces:
1) The threading works passable, if one strictly adheres to the instructions. They threaded the Yankz from above downwards, which some "mental work" requires especially when Marathonschnürung. Best put a shoe with lacing next inelastic and nachfädeln. The first shoe I needed a few attempts until I managed to fit top and bottom! The laces are long enough for a Marathonschnürung.
2) The threading can easily be carried out at not tightened shoe because a later readjustment is easily possible.
3) The lace ends are coated with a plastic film formed into needles (pins) which facilitate the threading in the holes. In the manual is recommended after threading and adjust trim the excess length and ends with some superglue, or by burning with a lighter, to prevent it from fraying. I did not do it, because this use in another shoe (threading!) Is unnecessarily difficult or impossible.
4) The loop at the top should (the small triangular plastic part) are hooked into the base clip. The catch, however, is so delicate that it only works if the loop is already biased slightly. I have solved differently (see photo).
5) If you your running shoes (especially in the heel) does not fit 100%, you can Yankz Shure Laces Thread in Marathonschnürung (see item 1). The rubber-laces of Yankz is somewhat less vigorous than that of Nathan Lock Laces, the heel hold is nevertheless acceptable and felt better than the Xtenex-Laces.
6) Once set and the shoe sits permanently well at the foot without pressing.
7) The T-Bar-called adjustment makes a somewhat filigree impression.
8) Attach the popular champion-time measuring chip (by threading) is difficult with the Yankz Shure Laces or inconvenient (unless you secured the chip eg with a cable tie).
Conclusion:
My personal favorite are the Nathan Lock Laces, closely followed by the Yankz Shure Laces and some distance behind the Xtenex-Laces.
UPDATE 2015-02-14: I'm running now for almost a year with Nathan Lock Laces, in the meantime in all my running shoes and I would not give it! No slackening of the clamping force of the rubber, no rising of tanka closure which holds as the first day. Really a top quality product!
