Hopefully we can keep you from going back to the dark side. The new Stabil CS is going to be called the Redeemer ISO. It's based on the Stabil, but has the ISOFIT system mentioned above that we have used so far in the Triumph, Hurricane and Zealot.
The Redeemer ISO also has the Powergrid+ midsole, so will feel a lot plusher too. I've just checked the line list and it's due in July, so you should be able to visit your regular running store to try a pair on. Full details will appear on our website as soon as the shoe is available.
It's up to you whether you take the insoles out. It depends on the type of orthoses you have. Personally, I put mine in and then put the insole (sockliner) back in over the top. My orthoses are hard, so I find that most comfortable. Others may prefer a different solution.
The ISOFIT system shouldn't interfere with most orthotics.
If you're used to the previous Triumphs, there's no reason that these won't work for you, but we'd strongly advise taking your orthoses along to the store when you try them on.
Ride 7 are neutral, yes. They're a different shape though, so again, you'd want to try them on.
Adot - the Triumph ISO can be used with Orthoses (I put mine in them no trouble, although I find the Ride 7 a better fit personally), but as Gideon says, the Echelon has greater volume in the midfoot and forefoot which allows more space for inserts.
By the way - ISO is the new fit system across the upper which provides a more tailored fit to a greater variety of foot shapes.
We currently offer the Triumph ISO (neutral) the Hurricane ISO (guidance) and the Zealot ISO (neutral with a 4mm drop). There's more info on these on www.saucony.co.uk
The Redeemer ISO (Stability / Motion Control) and the Echelon ISO will be along later this year,
We appreciate it is frustrating but we'd have to order several thousand pairs of the wide version of a style to "import" them, and there isn't that sort of demand for widths in even the most popular styles, let alone the Echelon.
As for international selling, that's a whole different legal kettle of fish with different partners owning the rights to sell the shoes in different regions/countries.
It doesn't help you, but maybe this goes some way to explain the situation.
The honest answer is that extra-wide-fit shoes have always been a disaster for us sales-wise in the UK (and Europe). There is good variation in fit in our range already. Sorry if you're not included in that.
