First 100km ultrarun - XT8 or MT3 to do it?

Hey runners

I owned a evadict xt8 and used for most of my trans hike and even for at least two 50km trail race.

I feel it is prefect aside from feeling hard and slightly uncomfortable after such long distance. The shoes now has 700km of mileage and I would like to add a new shoes, especially to my upcoming first 100km trail run and subsequent the other race, and for any long distance speed hike.

I live in tropical area so I would expecting the trail is somwhere mixture of mud, trail(majority, road (max 20%) a d of course, rivers.

I now presented with 4 choice.

1. Kiprun MT3 While decathlon promote XT8 is good in mud, I not sure if MT3 is good in mud and I seen reviews saying it is hard and not suitable for ultra marathon trail race.

2. Kailas Fuga EX3 Expensive but never tried before

3. Hoka Speedgoat Expensive but never tried before

4. back to xt8 So of my friend suggested me to buy a second xt8 because I already used to it.

Can everyone share you opinions and advice? Thanks in advance
