I'll attempt to do a comparison: Sidi OnRoad Sympatex .vs. Oxtar Matrix 2 Gore Tex.
Sidi's are about 5 years old or more -- in perfect shape and still keep me dry.
A note: I'm US size 9 shoe.
Sidi: 43 (Sidi says 43 = 9.5, 42= 8.5) Sidi fits me like a glove
Oxtar 42 (Oxtar says 43 = 10, 42 = 9.) Oxtar is a little loose in the arch area.
So -- with the same Euro size -- 43 Sidi's fit, 43 Oxtars are too big.
42 Sidi's too small, 42 Oxtars fit.
Left: Sidi Champion Air (
$160) great for hot rides, very vented. Kind of expensive for what you get.
Middle: Oxtar Matrix 2 Gore Tex (
$169.99)
Comfortable for all day walking wear, and has CE armor, can't vouch for the boots water proofness yet, but it does have a Gore-Tex liner -- so should be perfect.
Easy on-off half zipper, half velcro. The zipper is a liability for me -- it will break one day.
The Velcro closure at the top works fine.
It's a little shorter boot than the Sidi, and prefer it when I also have to walk-around alot.
Right: Sidi On Road Sympatex (
$260)
Comfortable for all day walking wear (slightly less comfy walking than the Oxtar)
Rode in a 9 hour downpour when the boots were several years old, and well worn -- no leaks.
Takes longer to put on, but can secure the top of the boot to your desire with the velcro tabs.
It's a little taller, but fits better over and under pants due to the adjustability in the top of the boot.
Bottom Line:
All day riding -- Sidi Sympatex. also the most durable/reliable
Riding then walking -- Oxtar
When it's Hot -- Sidi CA.
If I can only have one pair, I'd get the Oxtar.
If I can have 2 pair, Sidi On Road Sympatex and Champion Air.
