I’ve used Shimano MW81 for years. When they died last year i looked at others, as I sometimes get cold toes and wondered if different boots might help.
Tried some older Specialised shoes at Evans, but struggled to close the top of the show over my foot: I’ve got a very tall foot as I have a footbed to support my fallen arches. Was going to try a newer model in Hebden Bridge, but the mates I was with both said “don’t bother”, they’d both bought and then got rid of the same.
Treated myself to some 45nrth Fasterkatts. Very expensive, and not that much better (warmer) than the Shimano boots. The zip up the front popped open on the second ride, then again on the fourth and fifth. And sixth. Then they went back.
Ordered some Shimano MT91 and some Northwave Celsius from CRC. The northwave felt better so I’ve kept them and they’ve been great. They’ve a little more room in them so they do feel a little warmer, and I’ve room for thicker socks (on-one thickie merino) if need be
