I like the Salomon s/lab ultraglide, but I know a lot of people prefer the ultraglide 2
Hadn't seen these yet, very interesting coming from Salomon. I ran in the OG Ultra Glide (not S Lab) and liked them but found they just didn't hold up as well as prior Salomons. Those were the last pair from the brand I had a good experience with and have just moved on since.
I have Trabuco 13 and normal Ultra glide 1 and 3. They are all comfy ultra glide have more cushioning and would be better for 100k but I did a 55k recently in Tabucos and had zero issues.
S/lab UG V1.5 "Now with an improved heel design for a rub-free experience" The heel was causing people issues.
Aero Glide GRVL or if you want something a lot less bouncy Ultra Glide 3 or if you want something much firmer Genesis or if you want something much more expensive but still firm then S/Lab Genesis or if you want something less firm but still expensive with a little bit of bounce then S/Lab Ultra Glide 1.5. I would go with the GRVL personally, fantastic shoe.
Do they fit large/small? I loved my original ultraglides but the 2s were too a little too small for me.
S/Lab Ultra glides 1.0 x 2 S/Lab Ultra glides 1.5 x 1
S/Lab Ultra glides 1.0 x 2 S/Lab Ultra glides 1.5 x 1
One is the Ultra Glide with two different midsole foams and the sphere tech and one is a Shoe they initially named S/lab Ultra FDH with a fiberglass plate and a pretty dense Eva midsole foam that Francoise d‘haene helped create. This is Version 2 and they seemed to have upgraded the grip, deeper lugs and the fit from version 1 which was much needed because the first one had abysmal wet grip…Don’t ask how I know…Overall even if they improved grip not a shoe worth it’s pricetag if you ask me. Not sure what they changed in the Ultra Glide 1.5 but I’m sure hey must have fixed something..Probably the baggy upper or that last sphere under the big toe? I think there seems to be more than one thing that needed fixing with this shoe lol.
I have the 1.0 (got them at a good discount) and I love them. Just did a 50k in them. I heard about the heel rubbing and lockdown issues. There is a little bit of heel slippage but I wear high enough socks that it was never an issue. Completely agree on not pulling the laces too tight. Almost lost a toenail that way!
I’m the same as you and love my Saucony lineup for road. I have yet to find a trail shoe I love (have tried Hokas, Topos, and Saucony). The closest I’ve come to a trail shoe I like is the Salomon S/Lab Ultra Glide. I don’t love the lacing system. I don’t *love* them overall but was able to get through a 50k and training okay. Curious to hear recommendations and what you end up going with!
