Frequently Asked Questions

If your question is not answered in this FAQ, please don't hesistate to contact us.
Will the Slipstream be compatible with my pedals/bike?
The Slipstream is compatible with the SPD cleat - sold on our website - which will clip into almost every studio bike and outdoor bike. The SPD cleat is compatible with studios such as SoulCycle, CycleBar, Equinox, and many more. It will also work with many outdoor bikes as well. Just be sure to check that your pedal states that it is SPD compatible.

If you have a stationary bike at home or a personal bike you ride outdoors that is not compatible with SPD cleats, it is very simple to switch the type of pedals used so that you are able to clip in with our shoes.

The Slipstream is not compatible with a LOOK Delta cleat.
Do the shoes come with SPD cleats?
Our cycling shoes do not come with cleats. You may purchase them here.
How do I install SPD cleats into my shoes?
We always recommend having someone at your cycling studio install your cleats for you. They will have some expertise on where to align the cleats and how tightly they need to be fastened. But if you are planning to install them yourself, see our blog post for some tips.
What is your return policy?
All items will ship with a prepaid return label. TIEM will accept returns that have been sent back within 30 days of delivery.

To be eligible for a refund, your item(s) must be unused, in its original packaging, and in the same condition that you received it. Please note if you have installed an SPD cleat into your shoes, we cannot accept a return for any reason, even if the cleat is subsequently removed.
Can I exchange for a different size?
Of course you can return your shoes to us if they don't fit. Please follow the return policy outlined above, and place a separate order for the new size you need.
When will my order ship?
Orders placed before 1 PM EST will ship same day. Orders placed after that point will ship the next business day.
Do you ship internationally?
We now ship to select countries around the world! View the list of available countries here.
Can I use these shoes for running and other activities?
The Slipstream's primary intended use is cycling. We do not recommend you run in the Slipstream. Cycling shoes are constructed with a rigid sole plate that is ideal for cycling, but not suitable for running (due to this lack of flexibility, we also discourage driving a car in the Slipstream). However, the shoes can be comfortably worn while off the bike to walk around a gym or for other low-intensity use.
Where are your shoes sold?
You can purchase TIEM footwear online exclusively from our web store. Our shoes are also available at a number of cycling studios and shops across the country. Check out our list of retail stockists.
What is the sizing of the Slipstream like?
The Slipstream is currently only offered in women's sizing. It fits similarly to other athletic sneakers, but a snug fit is preferable for cycling. So our recommendation is generally to take a half size smaller than you would for a running or cross training sneaker.
Do you offer men's sizes?
Our shoes are currently only offered in women's sizes. We have had some men purchase shoes by sizing up 1 to 1.5 sizes from their men's size. (If you wear a 9.5 in men's, you should be able to fit into an 11 in women's sizing.)

If you would like to be notified when we add men's sizes in the future, please sign up for our newsletter.
