The thing with going to flats from SPDs is you’ve got to go all in. If you go half arsed, you are going to feel insecure and will not stick with it. You’ve got to give it a few months to get really confident with them, although I took to it quite quickly and rode my first flats alps trip within about 8 weeks.
The biggest problem I had was foot placement, I’d find I was concentrating more on my feet not being quite straight on the pedals than where I was going, that’s passed now.
I rode toe-clips, then moved to SPDs in 2002ish. I moved to flats last May and have not looked back. It’s been great fun and I’m now more in tune with the bike, plus I’m sure I would have had some nasty offs if I hadn’t been able to dab instantly on a few occasions.
I went with Five Ten Freerider shoes as I read they had the best grip. They haven’t disapointed.
I read DMR vaults were the best pedals, so went with those when there was a deal on at Cycle Surgery.
They have a great big platform and the pins give loads of grip.
Some people say they don’t like the Freeriders as they have too much grip and they can’t move their feed but coming from an SPD background I felt this was a good thing.
Freeriders are crap for winter as they act like sponges, I’ve got a pair of Shimano AM7s for cold, wet rides. They work really well but don’t have the same level of grip. I’ll be going back to my freeriders should the trails dry out.
All the best with your venture, hope it works out as well for you as it did for me.
