In reply to dread-i:
> I've got Speedgoat and Trailfly Ultra 300G, (I know that's not what you asked about I prefer the goats, as a good all round shoe. I've used them in snow, ice, mud & dry they seem to work out for me. The Trailflys are also good, 50g heavier & higher, with a slot for a gaiter strap in the sole. Be aware that the goats are narrow. Get the 2E width, version.
I have both of those...
Speedgoat: loved them, great all-round shoe, feel fast/poppy but still good level of cushioning for longer runs and even stretches of road. Good grip for most things, except really muddy. Despite all my other Hokas being true to size, I found these a little tight and I got blisters at about 10 miles. They've got worn in and I've now gone up to 13/14 miles without issues but I don't trust them for a marathon. I'd assumed I needed a half size bigger next time but perhaps you're right and it's the width that's the problem.
Trailfly Ultra 300G: marketed as an ultra shoe. Comfortable but boring and a bit heavy/clumpy to run in. Disappointed with the grip given G is for Graphene and I'd assumed they'd be quite good for that. Probably won't buy them again.
If I had to do 100 trail miles tomorrow (I've only done 50 mile events), I'd reach for my Hoka Challenger ATR for comfort/cushion and performance (i.e. no blisters to date). The main issue with these is the grip so if it was a muddier event, I'd be unsure what to wear! Probably I'd wish for a slightly roomier pair of the Speedgoat. On a 30 mile absolute mud fest of the most tedious kind, I wore the Challenger and was pretty tired from all the sliding around. Even the Speedgoat would have struggled. Needed big lugs for that one. So...
Dry road/forest track/trail mix: Challenger
More technical, mostly trail: Speedgoats with a little more room than my current pair!
Quite muddy for long sections: someone help me here?! I could do with a comfortable but very grippy shoe myself 🙂
