Im going to run more and more when spring and summer come, i bought my flyjumpers in autumn, so i never had a change to try them fully, but i can tell you all, I have never fallen with my flyjumpers, even when i have walk about 3-4 hour after my work everyday in about 2 month until snow came and ice everywhere on roads.
Many thanks to Jason for his wonderful rubber sole with rubber studs!!

I will try buy some safety gear from pro-jump.co.uk next week, wulf knee pads, GMX jacket, wrist pads, i also want bionicknee pads and spine protector but they are out of stock =/
i hope they can send it with royal mail like Jason did, i give "royal mail" my full trust
