Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
Salomon S/Lab Genesis Spine? Not full on waterproof but gaitered and water resistant. I do feel that a full gore-tex, gaitered shoe WOULD end up a bit of a sweat trap, as it's covering so much more than a regular shoe.
The tight heel lockdown I get from Salomon. Especially the current iteration of the S/Lab Genesis is very roomy at the toes but can get really locked down in midfoot/heel (mostly because of the Salomon lacing system). Iāve not worn them past 50k but know people that do. Maybe worth trying a few models?
To be honest there are almost certainly more comfortable options for multi-day, others will probably have better suggestions! It was just your comment about getting tight around the heels made me think itās worth trying out Salomons for the quick lace system!
This is so funny as I own all three. I wouldnāt do an ultra with new shoes so close⦠but if youāve got some 30k+ runs in the next few weeks maybe itād be fine? Anyway about the shoes. Genesis are in my daily rotation but havenāt done more than a half marathon in them. If I remember correctly theyāre quite low stack height? I remember my first few runs in them I could definitely feel it in my knees but theyāre fine after breaking in. I also own those exact color of Ultra Glides. They are beefy and feel quite heavy on the feet. My last race was 55km and 3500hm. I wore them as it was quite dry and all good but yeah definitely felt them towards the end. But at the same time I appreciated the cushion. I wouldnāt wear them again though on something so long and technical. Definitely definitely I had to size up in these. The NB i cannot run in. Iāve had them for a year as my daily sneaker but running in NB is a no go for me, my big toe just gets beaten up by the toe box.
I would second the Salomon or s/lab genesis. Wasnāt crazy about SG 6. Mafate speed 4 lite is good if you want a soft ride. Mount to Coast T1 is solid. People love prodigio pro (sadly didnāt work for my feet and felt a little bulky). Norda 001a also a strong option. Speedland GL:PDX if you want more bite. Havenāt tried it out yet but Kjerag 2 looks promising as well (Brut if you want more traction and less cushion)
Iāve run 2 with the s lab genesis and have LOVED them. A flat race in Texas and the bear 100.
Sadly, soft collars just donāt work for me. I really wanted to like the S/Lab Genesis, but I had to drop them. The ankle collar just doesnāt work for me my malleoli are extremely sensitive, and any contact causes irritation, even with socks on . Great shoe otherwise, but definitely not compatible with my anatomy.
With the Norwegian climate, for example, I would never have thought youād get along well with Salomons, since their outsole doesnāt perform well on wet rocks. I also have the Genesis, and if youāre looking for a precise fit, you could consider the Kjerag 2 even though youāre a bit heavy, if your limit is around 40 km, they might work fine. The Tomir are less agile, and Iāve never really gotten along with them. Then again, it depends on the terrain you use them on I do sky races, so I prioritize precision and grip over comfort.
I have the same problem as you and the shoes that block my heel best are the NNormal Kjerag and various Salomon models such as the Genesis
They are good everywhere except wet rocks on technical trails
NNormal (Kjerag) - Salomon (Ultra 3, Genesis) - Brooks (Catamount)
both the vanilla and slab genesis are good shoes but very different from the speedcross - one won't necessarily translate to the other. But worth a try.
Yeah Iāve been through 2 pairs and they only have about 100-200 good rocky US northeast running miles in them. I'm chonky for a trail runner though (190lb). The wet rock grip is atrocious anyway so Iāve moved on, however they are the still the comfiest shoe Iāve worn so itās a shame about the outsole. Have a look at the Genesis for a more modern outsole.
