First venture out on flats since I first started mtb'n 4 years ago, I've been happy to use spd's but I've realised to get the basics right (wheelies, bunny-hops, manuals) I'd be be better of using flats, got a cheap pair of flats but used some old Adidas trainers, pretty flimsy sole,
4-5 miles into my ride around pines and my feet were killing, so much so I cycled back to car to change back to spd's,
Do I need better support? I thought specific flat MTB shoes had flimsy soles??
What's the general gist?
