adidas Hydro-Pro: report 3 Introduction This report shows the status of the adidas Hydro-Pro Prototype 1 and Prototype 2 after 4 months of regular use during the week-ends, which means 25 approaches and 25 descents of canyons. Hydro-Pro Prototype 0

Walking hours and conditions of use The shoes were used for both the approach and the descent in the canyon. 25 canyons mean about 30 walking hours of approach and 75 hours of descent in the canyon for each shoe. The Hydro-Pro Prototype 1 were also used 1 week-end for hiking, about 7 hours walk on a mountain path, and about 32 hours as run shoes on a paved road. The shoes were used on both granite and limestone canyons. Our test-team of 6-11 canyoneers always tested one Hydro-Pro on one foot and one 5-10 or Bestard on the other foot to compare the comfort and the adhesion between the shoes.

Wear of the rubber sole Between the 3 pairs of shoes at our disposal (1 Hydro-Pro Prototype 1 and 2 Hydro-Pro Prototype 2), which did about the same number of canyons (the Hydro-Pro Prototype 1 has about 40 hours more walking life time), we could see some differences on the wear of the rubber sole.

The Hydro-Pro Prototype 1 seems to have less wear problems.

The Hydro-Pro Prototype 2 has a strong and unusual wear problem. It might be conducted on a probable sole injection-moulding problems?

Wear of the grey rubber The wear of the grey rubber is not a big problem and seems to be the same between the prototype 1 and 2. The prototype 1 has the advantage that has a colour that better hide the wear and give a better look at the shoe. The colour of the rubber of the prototype 2 give an impression of dirtiness compared to the proto 1. Picture below: Hydro-Pro Prototype 1

Wear of the seams The biggest problem by those shoes are the seams, that after only 25 canyons are nearly broken. Pictures below: Hydro-Pro Prototype 2

Rubber cracks Some rubber cracks were seen around some seams next to the bending part of the shoe as showed here below. Pictures below: Hydro-Pro Prototype 2

Shoe laces It is hard to say if it was a small defect or a general weak point, but one shoe shows some problems. Picture below: the first break

Picture below: laces assembly defect which might cause a stress on the seams.

Shoe strap The left shoes strap seems to be better loved by the canyonists because it allows to tighten stronger the shoe. Nevertheless it has a small rotstion problem as showed here below.

The begin of a wear problem is also noticeable as shown her below.

The velcro collect some dirtiness but it's not really a problem.

Shoe zip As already known, the zip has some problems because it opens itself. A first correction of the problem was already introduced on the left shoe, but a longer lace with velcro could be more helpful.

Some wear of the metallic zip is already noticeable but still not so significant to cause functional problems.

Regarding the type of zip we couldn't see any problem between the 3 models employed on the prototype 1 and 2.

Small stones and sand Between the shoe and the orange protection we noticed an amount of small stones and sand that might damage the orange protection of the shoe. It isn't a big problem, but it is difficult to take them out of the shoes.

Final comments Adhesion The adhesion of the Hydro-Pro seems to be good, at least as good as the competitor five-ten and a better adhesion than Bestard. Comfort The Hydro-Pro 2 is at the moment the best canyoning shoe we tested. No feet problems, pain or hurts during the approach and the canyon descent. The shell of the shoe is soft but stable enough to avoid ankle dislocations. The sole gives a good stability of the foot and it's soft enough to absorb very well even the strongest shocks during a run on a hard bottom. Warm and cold feet By cold water, the Hydro-Pro is much warmer than the 5-10 and the Bestard, due probably to the fact that there is no water exchange between the outside and the inside of the shoe. Till now we couldn't test the shoes in a warm canyon, so we can't say if this advantage might change in a disadvantage in mild water conditions. Wear of the rubber sole At the moment it's hard to say if the sole is too soft and weak. The Prototype 1 seams to be stronger, but there is also some differences between the wear of the Hydro-Pro 2 of Anna and the Hydro-Pro 2 of Luca, that might shows also that during the production there was a problem. Wear of the shell At the moment the shoe-shell seems to be strong and good enough. The only weakest point that absolutely need a correction are the seams, which are already nearly broken after only 25 canyons. Shoe laces It is hard to say if it was a small defect or a general weak point, but one shoe shows some problems. We could test only 3 pairs of shoes, one of them belong to the first prototype. A final conclusion with a so limited number of shoes has not a big sense and might set fruitless alarms and doubts. An endurance tests with a so small number of samples can only show a first tendency but doesn't means necessary that the first series of shoes follows the same tendency. To statistically evaluate in the best way the lifetime of the entire Hydro-Pro shoe it is really necessary to have some tenths of shoes at disposal and distribute them to a bright range of canyoneers with different backgrounds (professionals and non professionals), spread all over Europe and if necessary even all over the world. We have all the necessaries international contacts in case adidas would like to proceed in this direction. Always at you entirely disposal for any questions. Best regards Luca & Anna Nizzola
