Mudtalon Zero

I have the Mudtalon zero and they are a great orienteering shoe if metal studs and cramped toes are not your thing. They also feel bouncy and fun to run in. But the new Trailfly does not fit me at all and the midsole and grip felt a bit meh. For the stuff they're good at I'd rather wear a road shoe. My wife loves them though and did her latest ultra race in them.

Inov8 Mud Talon Zero. Absolute best trail shoe for mud in my opinion. Super light for a trail shoe as well, 255g and has a more natural fit on your feet than most main stream brands.

Inov-8's new lineup has wide options for every shoe. The one's I've used have been super durable shoes. I like the zero, but some of their thicker shoes with drop might align with your preferences better. Offensively ugly, but really good shoes. For sizing, always go by the bigger foot. Perfect would be to find a friend with opposite problem and split pairs, but that's pretty unlikely..

I don't know about Nordas myself, but about Inov-8. They quite recently brought back a zero-drop model, and they have wides available. I also get heel slippage with Altra 9+ wides, Trailfly zero has nice and snug heel. Trailfly Zero is basically same width in the toebox area, but shaped differently. Altras rub my big toe, Inov-8 squishes my little toe. For the same shoe size Altra is a bit longer and more voluminous, it could be half-a-size difference.

Would definitely look at Inov8 Imo they fit this kind of foot shape. They are also relatively minimal compared to most, even their max cushion models are not particularly high stack by today's standards. They have a zero drop version of most models also. If you have a narrow heel I'd go 'precision fit', they still have decent toebox, and good ground feel imo. Depending on terrain - trailfly are good on hardpack and low-medium technical trails, trail talons are the all rounder for varied terrain and softer surfaces, and mud talons are for mud and highly technical terrain.

It depends on how much mud and slippery stuff you are going to encounter. If it's 10 mins of mud in a 3 hour race then you can loose 3 mins by wearing your Pegasus trail if not then get 6mm+ lugs on your shoes. If it's ice then any trail shoes plus decent ice grippers/studs will work well.  I did a race at the weekend with roal to trail shoes plus grippers and it would have worked brilliantly had I bought decent grippers rather than use my wife's 5 year old £3 a pair rubber grippers with metal coils on. I do a triathlon in Scotland and wear my Inov8 mudtalons with 8mm lugs and they work really well. Half the run is mud or bog and I do not slip or slide. I've tried it in Nike Ultrafly and I was a lot slower! The most efficient trail shoes on runrepeat seem to be the Saucony Endorphin Edge and the Xodus Ultra 3. So if one of those has enough grip I would maybe give that a try. The best shoe is the one you already own, so if you have the Pegasus trail just wear it... But it is a very middling trail shoe. It does every pretty badly. It's not massively comfy, it's relatively slow and it's good poor grip... But you can look up your own metric see what you might like then try on a couple of them 🤞.
